Versuchsvorschrift
203.9 mg of 17-cyclopropylmethyl-3-tert-butyldimethylsilyloxy-14β-hydroxy-4,5α-epoxy-6α-(methylaminomorphinan 108 obtained in reference example 91 was dissolved in 3 ml of pyridine followed by the addition of 124 mg of 3,4-dichlorophenylmethanesufonylchloride and stirring for 30 minutes at room temperature. After concentrating the reaction system, 3 ml of saturated aqueous sodium bicarbonate and 3 ml of chloroform were added to separate layers, after which the aqueous layer was extracted twice with 3 ml of chloroform. After drying with anhydrous sodium sulfate, the organic layer was concentrated to obtain the oily crude product. This was then purified with silica gel column chromatography (30 g benzene/ethyl acetate=5/1) to obtain 235.4 mg of the target compound (yield: 78%).
