Procedure

A solution of Example 32B (10 g, 34.8 mmol), in pyridine (50 mL) at room temperature was treated with methanesulfonyl chloride (2.7 mL, 34.8 mmol), stirred at room temperature for 16 hours, and concentrated. The concentrate was treated with ethyl acetate (100 mL), and the resulting solution was washed with 2N HCl, dried (Na2SO4), filtered, and concentrated. The concentrate was recrystallized from ethanol to provide the desired product. MS (ESI(−)Q1MS) m/z 394 (M−H)−.
