실험 절차

460 mg (2 mmol) of 1-(chloromethyl)-4-(2-phenylethyl)benzene [preparation according to M. Carrara et al., Arzneim. Forsch. 47 (7), 803-809 (1997)] and 414 mg (3 mmol) of anhydrous potassium carbonate are added to a solution of 411 mg (1 mmol) of methyl 4-[(3E)-2-[2-(4-cyanophenyl)ethyl]-4-(2-hydroxyphenyl)but-3-en-1-yl]benzoate in 10 ml of dry acetonitrile, and the mixture is heated under reflux for 12 hours. The mixture is then evaporated to dryness. The residue is taken up in ethyl acetate, washed with water and with saturated sodium chloride solution and dried over sodium sulphate. After filtration, the organic phase is evaporated and the resulting crude product is purified by preparative HPLC. 431 mg (0.7 mmol, 65% yield) of a solid are obtained.
