Participants

Reaction Steps

To a mixture of tert-butyl 3-(trifluoromethyl)piperazine-1-carboxylate (72 mg, 0.28 mmol) and 2-methoxy-4-(2-oxoethyl)benzonitrile (50 mg, 0.28 mmol) in methanol (2.5 mL) at 0° C. was added sodium cyanoborohydride (25 mg, 0.40 mmol) and the mixture was stirred at room temperature for 12 hours. The reaction mixture was concentrated and purified by column chromatography (4->30% ethyl acetate:hexanes) to provide tert-butyl 4-[2-(4-cyano-3-methoxyphenyl)ethyl]-3-(trifluoromethyl)piperazine-1-carboxylate. LC-MS (IE, m/z): 414.4 [M+1]+.
