Reaction Steps
A solution of Example 42J (650 mg, 1.53 mmol) in dioxane (30 mL) at room temperature was treated with 10% K2CO3 (10 mL) and methyl chloroformate (700 mg) and stirred for 16 hours. The mixture was treated with water and extracted with dichloromethane. The combined extracts were washed sequentially with 5% HCl, water, and brine, dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with dichloromethane to provide the desired product.
