Participants

Reaction Steps

A solution of Example 173A (54.1 mg, 0.1 mmol) in NMP (2 mL) at room temperature was treated with phenethylisocyanate (0.2 mmol), stirred for 18 hours, diluted with water, and centrifuged. The solid was purified by flash column chromatography on silica gel with 0-5% methanol/dichloromethane to provide the desired product.
