Procedure

289 mg (2.5 mmol) Methansulfonylchloride was added to a stirred solution of 470 mg (2.3 mmol) A3 and 255 mg (2.5 mmol) triethylamine in dry 20 ml dichloromethane, and the solution was stirred at room temperature overnight. After hydrolysis (15 ml), the phases were separated and the organic layer was washed with saturated NaCl (10 ml) and dried over magnesium sulfate. 236 mg (0.9 mmol) A17 was obtained by column chromatography on SiGel (iso-hexane/ethyl acetate 9:1).
