Flashvacuum pyrolysis of methyl N-methyl-N-nitrosoanthranilate leads to elimination of nitric oxide and disproportionation of the formed N-radical to 7-(methylamino)phthalide and methyl N-methylanthranilate. This transformation was found to be a convenient, solvent-free method for the preparation of 7-(methylamino)phthalides. An alternative route through pyrolysis of N-benzyl-N-methyl anthranilates
