Reaction Steps

2-(3-(benzyloxy)pyridin-2-yl)-3-(1-(3,4-difluorophenyl)propan-2-yl)-5-(trifluoromethyl)-2,3-dihydropyrido[4,3-d]pyrimidin-4(1H)-one (12.1 grams, 21.8 mmol) prepared by the same reactions conditions described above was dissolved in 300 mL of ethanol and added to a parr bottle that contained 10% Pd(C). The mixture was subjected to hydrogenation condition (45 psi) for two hours. At this time, the reaction mixture was filtered through Celite and washed with ethanol. The fitrate was concentrated in vacuo and purified by silica gel chromatography to afford a pale yellow foam of 3-(1-(3,4-difluorophenyl)propan-2-yl)-2-(3-hydroxypyridin-2-yl)-5-(trifluoromethyl)-2,3-dihydropyrido[4,3-d]pyrimidin-4(1H)-one.
