Versuchsvorschrift
A suspension of [3-fluoro-4-(4-methyl-imidazol-1-yl)-phenyl]-thiourea (125 mg, 0.50 mmol) and of 2-bromo-6-phenyl-cyclohexanone (253 mg, 1.00 mmol) in ethanol (4 mL) was stirred at room temperature for 30 minutes and then heated for two days to reflux under an atmosphere of nitrogen. After cooling to room temperature the solvent was evaporated under reduced pressure and the residue was purified on silica gel using dichloromethane and then dichloromethane/methanol (19:1 v/v) as eluent to yield the title compound (200 mg, 99%) as a white solid. MS ISP (m/e): 405.4 (100) [(M+H)+]. 1H NMR (DMSO-D6, 300 MHz): δ (ppm)=10.40 (s, 1H), 7.73 (s, 1H), 7.67 (d, 1H), 7.38 (t, 1H), 7.32 (t, 2H), 7.10-7.21 (m, 4H), 4.04 (m, 1H), 2.70 (m, 2H), 2.13 (s, 3H), 2.11 (m, 1H), 1.70-1.89 (m, 3H).
