Conditions

Temperature: -20 °C

Procedure

The product from Example 207B (2.23 g, 7.12 mmol) and triethylamine (2.98 mL, 21.36 mmol) were combined in dichloromethane (50 mL). The mixture was cooled to −20° C. and methanesulfonyl chloride (1.383 mL, 17.80 mmol) was added. The mixture was stirred at room temperature for 1 hour. The solvent was evaporated to give the title product (approx 3.34 g) which was directly used for the next reaction.
