Versuchsvorschrift

A mixture of 5.4 g of cis-2,3-bis(methanesulfonyloxymethyl)oxirane, 2 ml of 3-bromoaniline, 4.3 g of anhydrous potassium carbonate and 30 ml of N,N-dimethylformamide was stirred under nitrogen atmosphere at 60° C. for 2 hours and at 110° C. for 2 hours. The reaction mixture was extracted with ethyl acetate-water, and the organic layer was washed with water and brine, dried over anhydrous magnesium sulfate and then evaporated. The residue was purified by silica gel column chromatography with 5–10% ethyl acetate/hexane, to give 420 mg of the title compound.
