The crude 4-(2-Oxoethyl)benzonitrile (100 mg, 0.69 mmol) was treated with 1-[2-(4-nitrophenyl)ethyl]piperazin-2-one (197 mg, 0.69 mmol) and titanium(IV) isopropoxide (2.0 mL). After stirring the mixture for 15 minutes, ethanol and sodium cyanoborohydride was added into the reaction. The mixture was allowed to stir for 4 hours. The reaction was diluted with ethyl acetate, washed with brine, dried over sodium sulfate, and concentrated to give the crude residue. The desired product was purified by mass-directed reverse phase HPLC (AcCN-Water with 0.1% TFA). LC-MS (IE, m/z): 378 [M+1]+.
