实验步骤: To a solution of 2-(4-hydroxyphenyl)-4-[4-[3-(1-imidazolyl)propyl]phenoxymethyl]oxazole (250 mg) in N,N-dimethylformamide (10 ml) was added sodium hydride (oily, 60%, 30 mg) and stirred at room temperature for one hour, to which chlorodiphenylmethane (270 mg) was added and stirred at 80° C. for 6 hours. The reaction mixture was poured into water, and extracted with ethyl acetate. The ethyl acetate layer was washed with 1N-sodium hydroxide and water, dried (MgSO4), and concentrated under reduced pressure. The residue was subjected to a silica gel column chromatography. From the fraction eluted with ethyl acetate-methanol (50:1, v/v), crystals of 2-(4-diphenylmethoxyphenyl)-4-[4-[3-(1-imidazolyl)propyl]phenoxymethyl]oxazole (155 mg, 43%) was obtained. Recrystallization from ethyl acetate-hexane gave colorless prisms, mp 106-107° C. was added extracted with ethyl acetate The ethyl acetate layer was washed with 1N-sodium hydroxide and water dried (MgSO4) concentrated under reduced pressure From the fraction eluted with ethyl acetate-methanol (50:1
