Reaction Steps

N-cyclopropyl-3-[8-(2,6-difluorophenyl)-2-(methylsulfonyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl]-4-methylbenzamide (0.1 g, 0.2 mmol) is dissolved in DMF (10 mL) and (1H-imidazol-2-ylmethyl)amine dihydrochloride (0.053 g, 0.4 mmol) is added followed by triethylamine (0.167 mL, 1.2 mmol). The mixture is heated to about 60° C. for about 3 h. The reaction is judged to be complete by LCMS and the crude mixture is purified via reversed-phase HPLC. HPLC indicates 95% pure (254 nm) and the desired product is obtained as a white powder (54 mg, 50%): LC-MS m/z 528 (M+H)+, 1.45 min (ret time).
