実験手順

In a 25 mL 3-neck RBF equipped with a rubber septum, N-(3-((5-fluoro-2-((4-((2-methoxyethoxy)methoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)acrylamide (0.180 g) was taken and TFA (1.0 mL) was added drop wise at room temperature under stirring. The reaction mixture was further stirred for 30 min. Completion of reaction was monitored by TLC using CHCl3:MeOH (9.5:0.5). After completion, the reaction mixture was quenched in water. The aqueous solution was basified with saturated sodium bicarbonate solution. The product was extracted into DCM, washed with water and dried over sodium sulfate. The solvent was evaporated under reduced pressure. The crude product was treated with DBU and 75 mg of product was collected. This was further purified by preparative TLC using CHCl3:MeOH (9.5:0.5) as a mobile phase to give 10 mg of N-(3-((5-fluoro-2-((4-hydroxyphenyl)amino)pyrimidin-4-yl)amino)phenyl)acrylamide. M+1=365.9 1H NMR: DMSO-d6 (400 MHz) 5.73-5.76 (dd, 1H, J=2, 8), 6.23-6.28 (dd, 1H, J=2, 18.8), 6.48-6.55 (m, 1H), 6.59. 6.61 (d, 2H, J=8.8), 7.22-7.261 (t, 1H, J=8.16), 7.40-7.51 (m, 4H), 8.03-8.04 (d, 2H, J=3.6), 8.426 (s, 1H), 8.902 (s, 1H), 9.331 (s, 1H), 10.26 (s, 1H).
