Reaction Steps

A solution of chlorosulfonyl isocyanate (24.5 μL, 0.281 mmol) in dichloromethane (2 mL) was treated dropwise with benzyl alcohol (29 μL, 0.281 mmol) at 25° C., stirred at 25° C. for 30 min, treated with a solution of the product of Example 205 (100 mg, 0.234 mmol) and triethylamine (130 μL, 0.936 mmol) in dichloromethane (3 mL)and stirred for 2 hrs at 25° C. The reaction mixture was treated with dichloromethane (10 mL) and 1N aqueous hydrochloric acid (10 mL). The resulting organic layer was separated and dried over magnesium sulfate, filtered, and concentrated under reduced pressure to provide the title compound (122 mg, 81%).
