実験手順

A mixture of 5-(2-(3,4-dichlorophenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazole-2(3H)-thione (760 mg, 2 mmol), 4-(bromomethyl)-3,5-difluorobenzonitrile (464 mg, 2 mmol) and K2CO3 (414 mg, 3 mmol) in acetone (10 mL) was stirred at 56° C. for 4 h. After cooling, the solids were removed by filtration and rinsed with acetone. The combined filtrates were concentrated and purified by flash chromatography, eluting with EtOAc-Hexane (1:1) to afford the title compound (89 mg). 1H NMR (400 MHz, CDCl3) δ 7.26 (t, J=4.2, 2H), 7.17 (d, J=6.5, 2H), 7.03 (d, J=2.2, 1H), 6.88-6.79 (m, 3H), 6.50-6.44 (m, 2H), 4.08 (d, J=9.1, 2H), 2.04 (s, 1H), 1.49 (s, 7H); MS (EI) m/z 432 (MH+).
