实验步骤: A solution of KOH (9.4 g) in water (85 ml) was added to a stirred solution of the product from step (b) (5.1 g) in toluene (150 ml) at 0° C. A solution of phosgene (9.8 g) in toluene (78.4 ml=12.5% w/v) was added dropwise over 15 minutes and the mixture brought to room temperature, then stirred overnight. The aqueous phase was separated and extracted with ethyl acetate. The combined extracts were evaporated in vacuo to give the desired product as a white solid (2.2 g), mp 106°-108° C. Elemental anaylsis was consistent with the proposed structure. brought to room temperature The aqueous phase was separated extracted with ethyl acetate The combined extracts were evaporated in vacuo
