Versuchsvorschrift

To a solution of the title compound of Step B (Example 1) (0.4 g, 0.96 mmol) in 8 ml methylene chloride cooled to 0° C. was added triethylamine (0.15 g) and dibutylaminosulfenylchloride (0.2 g). The reaction mixture was, warmed to room temperature and stirred for one hour. The mixture was subjected to silica gel column chromatography using hexane-ether (6:1) as the eluent. The title compound was obtained (0.24 g) in high purity.
