Reaction Steps

A solution of 6-benzyl-N-(2,2-difluoroethyl)-2-(4-(2,4-difluorophenoxyl)piperidin-1-yl)-5,6,7,8-tetrahydropyrido[3,4-b]pyrazin-3-amine TFA salt (132.5 mg, 0.210 mmol) in THF (2.1 mL) was treated with Pd(OH)2 (20 wt %, 29.6 mg, 0.042 mmol). Hydrogen gas (balloon) was bubbled through the reaction mixture for 5 min. The vent needle was removed and the reaction was stirred under hydrogen atmosphere for 1 h. The reaction mixture was opened to air and was filtered through a pad of Celite™, eluting with EtOAc and MeOH. The filtrate was concentrated under reduced pressure to give the title compound as a TFA salt (114 mg), which was used without further purification. ESI-MS m/z [M+H]+ 426.5.
