Participants

Reaction Steps

A solution of Example 43F (0.119 g, 0.240 mmol), mesyl chloride (0.075 mL, 0.970 mmol), and pyridine (0.157 mL, 1.94 mmol) in acetone (3 mL) was stirred at 25° C. for 18 hours. The solution was partitioned between ethyl acetate and dilute citric acid and the layers were separated. The ethyl acetate layer was dried with sodium sulfate, filtered, and concentrated in vacuo. The residue was chromatographed on silica gel eluting with methylene chloride and 2.5% methanol in methylene chloride to give a yellow solid.
