Procedure

To a stirred solution of the title compound of Example 13 (1.0 g) in pyridine (15 mL) under nitrogen at approximately 5° C. (ice water bath) was added dropwise via syringe methanesulfonyl chloride (0.28 mL). The ice bath was removed, and the reaction was stirred at ambient temperature for 2 hours. The reaction was then evaporated under vacuum, and the residue was treated with 1M HCl. The insoluble product was collected by filtration, washed twice with 1M HCl, and then with water. The solid was suspended in methanol, heated to reflux on a steam bath, cooled to room temperature, and the product was collected by filtration. Recrystallization from acetonitrile yielded the title compound as a pinkish solid. Mp: 211°-212° C.
