Reaction Steps

To a mixture of 4-(5-(trifluoromethyl)-2-{4-[3-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}-1H-benzimidazol-7-yl)benzylamine (172 mg, 0.33 mmol, Example 75) and acetone (1 mL) in chloroform (5 mL) were added NaBH(OAc)3 (211 mg, 1 mmol) and one drop of acetic acid. The mixture was stirred at room temperature for 2 h, diluted with dichloromethane (30 mL), washed with satd aq. NaHCO3 solution (25 mL), dried over Na2SO4, and filtered. The filtrate was evaporated and the residue was purified by silica gel column chromatography, eluting with 5% MeOH in dichloromethane to give the title compound as white amorphous solid. MS (ESI, pos. ion) m/z: 563 (M+1), (ESI, neg. ion)
