Procedure

To a solution of the compound of Example 263 (0.4 g) and 0.5 mL triethylamine in 10 mL CH2Cl2 at 0° C. was added methanesulfonyl chloride (0.2 mL) and the resulting reaction solution was stirred at RT for 2 h. Water was added and the two layers were separated. The organic solution was washed with brine, dried and concentrated. Purification by flash chromatography with 30% ethyl acetate-hexane gave 0.4 g of product as a white solid. m.p. 82°-86° C.
