Reaction Steps
A solution of chlorosulfonyl isocyanate (33 mg, 0.23 mmol) in dichloromethane (8 mL) was cooled to 0° C. and 2-chloroethanol (18.8 mg, 0.23 mmol) was added dropwise. The mixture was stirred at 0° C. for 90 minutes followed by the addition of a solution containing the product of Example 205 (100 mg, 0.23 mmol) and triethylamine (71 mg, 0.70 mmol) in dichloromethane (2 mL). The mixture was stirred for 24 hrs at 25° C. then partititioned between dichloromethane (25 mL) and 1N aqueous hydrochloric acid (20 mL). The resulting organic layer was separated and dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide the title compound (96 mg, 67%).
