Archie Battersbee’s parents have confirmed they have submitted an application to the European Court of Human Rights in a bid to postpone the withdrawal of his life support on Wednesday.
The 12-year-old has been in a coma since he was found unconscious by his mother in April.
He is currently being kept alive by a combination of ventilation and drug treatments at the Royal London Hospital in Whitechapel, East London.
A spokesman for the charity which is supporting the family confirmed that the application was submitted shortly before the 9am deadline they had to meet to prevent Archie's treatment being stopped at 11am.
His mother Hollie Dance said: "We are very relieved, we are having to battle every decision with the hospital.
"We now hope and pray that the ECHR will look favourably on the application. We will not give up on Archie until the end."
The trust running the hospital where Archie is being treated said it would not withdraw life support until the court appeal had concluded.
Alistair Chesser, chief medical officer for Barts Health NHS Trust, said: "Our deepest sympathies remain with Archie's family and we aim to provide the best possible support to everyone at this difficult time.
As directed by the courts, we will work with the family to prepare for the withdrawal of treatment, but we will make no changes to Archie's care until the outstanding legal issues are resolved."
His parents, Ms Dance and Paul Battersbee, were granted a Court of Appeal hearing on Monday after the government asked judges to urgently consider a request from a UN committee to keep treating Archie while it reviews his case.
However, three judges refused to postpone the withdrawal of life-sustaining treatment beyond midday on Tuesday.
They also refused to grant permission to appeal against their ruling at the Supreme Court.
Ms Dance and Mr Battersbee filed an application directly with the Supreme Court, asking for his treatment to continue so the UN Committee on the Rights of Persons with Disabilities (UNCRPD) could have time to consider their complaint, made last week.
But, refusing permission to appeal, a panel of three justices concluded the Court of Appeal “made the correct decision”.
On Tuesday evening, Ms Dance said Barts Health NHS Trust would begin to withdraw Archie’s life support on Wednesday at 11am unless the family has submitted an application to the European Court of Human Rights by 9am.
Ms Dance told the PA news agency: “Our solicitors will be filing to the European Court of Human Rights. They’ve been given a strict timeline of 9am. Again, no time whatsoever.
“Every single court case we’ve had we’ve had no time at all, one or two days to prepare and get the whole case together.”
She said that their legal team described the attitude of the hospital as “brutal” and had claimed he had been refused a hospice.
Supreme Court judges said they have “great sympathy” Archie’s parents, but added that there is “no prospect of any meaningful recovery”.
Alistair Chesser, chief medical officer for Barts Health NHS Trust, said: “Our deepest sympathies remain with Archie’s family.
“As directed by the courts, we will now work with the family to prepare for the withdrawal of treatment.
“We aim to provide the best possible support to everyone at this difficult time.”
Archie was found unconscious at his home by his mother on April 7 and has not regained consciousness since. She believes he was taking part in an online challenge.

31 May - MRI scans conducted.
6-8 June - Court hearing held to decide if Archie's life support treatment should continue. Specialists say it is highly likely that Archie is "brain stem dead", and that tests conducted showed no discernible brain activity, revealing "significant areas of tissue necrosis".

29 June - Three Court of Appeal judges uphold the family's appeal, and order a fresh hearing to take place at the High Court in front of a different judge.

15 July - Mr Justice Hayden concludes that doctors can lawfully stop providing life-support treatment, calling the medical evidence "compelling and unanimous".

25 July - Three Court of Appeal judges hear the appeal, but back Mr Justice Hayden's ruling that treatment can end as it is in Archie's best interests. A stay is put in place for Archie's treatment to continue until 2pm on 27 July.
27 July - As the stay expires, Archie's family are given a further 24 hours to appeal to European Court of Human Rights.

But Court of Appeal judges refuses to postpone the withdrawal of life-support, extending it only until midday on Tuesday, 2 August. The most senior family judge in the country says the UN convention is an "unconventional international treaty and is not part of UK law", and that it continues to be in Archie's best interests to stop treatment.
2 August - Archie’s parents are refused permission to appeal against the latest ruling at the Supreme Court. Ms Dance says Barts Health NHS Trust will begin to withdraw Archie’s life support on August 3 at 11am unless the family have submitted an application to the European Court of Human Rights by 9am that day.
