Procedure

A solution of 3-(4-hydroxy-3,5-dimethyl-phenyl)-1-(4-phenyl-5-propyl-thiophen-2-yl)-propan-1-one (250 mg, 0.661 mmol) in 2-propanol (2 mL) and 3 N aq. NaOH (1 mL) is treated with epichlorohydrine (122 mg, 1.32 mmol) and the mixture is stirred at rt for 18 h, then diluted with water and extracted with EA. The solvent of the organic extract is evaporated to give crude 3-(3,5-dimethyl-4-oxiranylmethoxy-phenyl)-1-(4-phenyl-5-propyl-thiophen-2-yl)-propan-1-one (257 mg) as a yellow oil; LC-MS: tR=1.18 min, [M+1]+=435.20.
