Reaction Steps

Ethanol (12 mL) was added to 2-(3,5-dimethyl-1H-indazol-4-yl)-6-(5-isopropyl-2-methylphenyl)-4-methoxy-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (2.07 g, 3.47 mmol), followed by 12 N aqueous hydrochloric acid (12 mL). The mixture was then heated at 85° C. for 18 h. The mixture was cooled to room temperature, diluted with dichloromethane and slowly neutralized with saturated aqueous sodium bicarbonate. The resulting layers were separated and the aqueous layers were extracted with dichloromethane. The organic layers were combined. The combined organics were dried and concentrated. The residue was purified by FCC (0-100% EtOAc/heptane) to provide 2-(3,5-dimethyl-1H-indazol-4-yl)-6-(5-isopropyl-2-methylphenyl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-4-ol. MS (ESI+) m/z 428.3 (M+H)+.
