Reaction Steps

To the compound 3-[2-{[3-(diethylamino)propyl]amino}-8-(2,6-difluorophenyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl]-4-methylbenzoic acid (26 mg, 0.05 mmol) in DMF (0.5 mL) were added HBTU (28 mg, 0.075 mmol), triethylamine (21.1 uL, 0.15 mmol) and aniline (9.1 uL, 0.1 mmol). The mixture was stirred at rt overnight. To the mixture was added 5 mL dichloromethane and 2 mL water, stirred for 3 min. The organic layer was loaded onto the silica gel column. Chromatography (90% methylene chloride/7% MeOH/3% ammonia) afforded the title compound (9 mg, 30%). LC-MS m/z 597 (M+H)+.
