A mixture of 6-Oxo-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (24 mg, 0.14 mmol) and 1-[2-(4-nitrophenyl)ethyl]piperazin-2-one (20 mg, 0.070 mmol) was treated with titanium(IV) isopropoxide (0.10 ml, 0.35 mmol) for 30 minutes. Then the reaction was diluted with ethanol (5 mL), and sodium cyanoborohydride (44 mg, 0.70 mmol) was added. The reaction was stirred at RT overnight. The reaction was diluted with EtOAc, washed with brine, dried over sodium sulfate, and concentrated to give the crude residue. The desired product was purified by reverse phase HPLC (AcCN-Water with 0.1% TFA). LC-MS (IE, m/z): 405 [M+1]+.
