実験手順

To a solution of 7-((4-methoxybenzyl)(methyl)amino)-3-(5-amino-2,4-difluorophenyl)-1-methyl-1,6-naphthyridin-2(1H)-one (3 g, 6.8 mmol) in DCM (100 mL) was added CF3COOH (20 mL) and the resulting mixture was stirred at 25° C. for 6 h. Water was added and the mixture was extracted with water. The combined aqueous layers were neutralized with NH3H2O to pH 7. The precipitate was collected by filtration and dried to give 3-(5-amino-2,4-difluorophenyl)-1-methyl-7-(methylamino)-1,6-naphthyridin-2(1H)-one (661 mg, 30% yield). 1H NMR (300 MHz, DMSO-d6): δ 8.39 (s, 1 H), 7.78 (s, 1 H), 7.08-6.93 (m, 2 H), 6.80 (dd, J=10.2, 8.1 Hz, 1H), 6.16 (s, 1 H), 5.00 (s, 2 H), 3.50 (s, 3 H), 2.84 (d, J=4.8 Hz, 3 H); MS (ESI) m/z: 317.0[M+H]+.
