Procedure

0.254 gram (1.4 mmole, 1.0 eq.) of product from step D was dissolved in 7 ml of 1,2-dichloroethane, after which 0.20 ml of benzoyl chloride and 0.225 gram aluminum (III) chloride (1.7 mmole, 1.2 eq. each) were added. Stirred at room temperature under nitrogen atmosphere for 75 minutes, then quenched with aqueous potassium carbonate. Diluted further with water and extracted 3× with dichloromethane. The combined organics were dried over sodium sulfate, filtered and evaporated. The resulting crude material was chromatographed to give 0.38 gram (95% yield) of the title compound.
