Procedure

Compound (H) (200 mg; 0.84 mmols) has been dissolved in anhydrous pyridine (3 ml). The thus obtained solution has been cooled to 0° C. and added with freshly distilled methanesulfonyl chloride (0.06 ml). The solution has been maintained at 0° C. overnight and then diluted with an aqueous solution of hydrochloric acid (stoichiometric amount with respect to pyridine) and ice. After extraction with ethyl acetate, the organic extract has been dried over sodium sulfate and evaporated in vacuo to afford crude (J); yield, 85-90%.
