Acetic anhydride (0.016 mL, 0.17 mmol) was added to a solution of 4-(1-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)-N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine in DCM (1 mL) and stirred for one hour. The solvent was evaporated and the crude product was purified on prepHPLC yielding 1-(4-(1-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)ethanone (14.00 mg, 16.03%).
