A suspension of [3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-thiourea (100 mg, 0.38 mmol) and of crude 6-bromo-2-(3-methoxy-phenyl)-2-propyl-cyclohexanone (126 mg, 0.39 mmol) in ethanol (5 mL) was heated to reflux under an atmosphere of nitrogen for 2 days. After cooling to room temperature the solvent was evaporated under reduced pressure and the residue was purified by reversed preparative HPLC using acetonitril/water (0.1% formic acid) to yield the title compound (5 mg, 3%) as a yellow solid. MS ISP (m/e): 489.3 (100) [(M+H)−]. 1H NMR (CDCl3, 300 MHz): δ (ppm)=7.64 (s, 1H), 7.58 (d, 1H), 7.12-7.19 (m, 2H), 6.68-6.89 (m, 5H), 3.76 (s, 6H), 2.67 (m, 2H), 2.29 (s, 3H), 1.05-2.16 (m, 8H), 0.89 (t, 3H).
