実験手順

To a solution of the title compound of Step B (2.0 g, 4.8 mmol) in 50 ml methylene chloride cooled to 0° C. was added triethylamine (1.0 g, 0.01 mol) and ethyl (chlorosulfenyl)(1-methylethyl)carbamate from Step D (1.4 g, 7.7 mmol). The mixture was allowed to warm to room temperature and stirred for one hour. The crude mixture was purified by silica column chromatography using ether-hexane (1:2) as eluent. The title compound (2.38 g) was obtained in about 90% purity (mp: 130°-134°). Extraction of the product with ether-hexane (2:1) gave 1.8 g of a highly pure material mp: 139°-140° C.
