Procedure

A mixture (6S)-6-piperazin-1-yl-5,6,7,8-tetrahydronaphthalene-2-carbonitrile (0.31 mg, 0.13 mmol), 1-(2-bromoethyl)-4-nitrobenzene (80 mg, 0.35 mmol), and triethylamine (0.15 mL, 1.1 mmol) in DMF was heated to 60° C. for 30 hours. LC showed formation of the desired product. The reaction was diluted with EtOAc, washed with water and brine, dried over MgSO4, and purified by MPLC to deliver 13 mg of (65)-6-{4-[2-(4-nitrophenyl)ethyl]piperazin-1-yl}-5,6,7,8-tetrahydronaphthalene-2-carbonitrile. LC-MS (IE, m/z): 391 [M+1]+. (0.083 μM)
