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 (40 mg, 0.074 mmol) in methylene chloride (2 mL) were added HBTU (30 mg, 0.079 mmol) and ethylamine (0.19 mL, 0.37 mmol, 2.0M soln in THF). The mixture was stirred at rt overnight. Solvent was removed by rotovap. Separation by chromatography (90% methylene chloride/7% MeOH/3% ammonia) afforded the title compound (17 mg, 40%). LC-MS m/z 549 (M+H)+.
