実験手順
0.5 g of (RS)-3-[4-(trans-4-hydroxy-cyclohexyl)-phenyl]-5-methoxymethyl-oxazolidin-2-one in 5 ml of ethyldiisopropylamine was heated with 0.35 ml of chlorodiphenylmethane to 100° and stirred at this temperature for 7 hours. The reaction mixture was cooled, acidified with 1N hydrochloric acid and extracted with ethyl acetate. The organic phase was washed neutral with water, dried with magnesium sulfate and concentrated. The residue (0.7 g) was chromatographed on a 30-fold amount of silica gel with methylene chloride/ethyl acetate mixtures. 0.3 g of (RS)-3-[4-(trans-4-benzhydryloxy-cyclohexyl)-phenyl]-5-methoxymethyl-oxazolidin-2-one was obtained as colorless crystals. M.p.: 146°-148°.
