Procedure

To a vigorously stirred solution of Example 45E (1 g, 2.59 mmol) in dichloromethane (5.19 mL) was added triethylamine (0.542 mL, 3.89 mmol) and methanesulfonyl chloride (0.253 mL, 3.24 mmol). The reaction was stirred for 10 minutes and then quenched with brine, extracted twice with dichloromethane, dried over sodium sulfate, and the solvent was evaporated to afford the title compound. MS (ESI+) m/z 464.1 (M+H)+.
