Procedure
Methanesulfonylchloride (29.23 mg; 0.26 mmol; 0.6 eq.) was added to a solution of Example 41 (75 mg; 0.43 mmol; 1 eq.) in pyridine (1 mL) and the resulting solution was stirred at room temperature for 36 hours then concentrated in vacuo. The residue was purified by column chromatography (c-hexane/ethyl acetate, 70/30) followed by crystallization from ethyl acetate/n-pentane to afford the title compound as an off-white solid.
