A solution of the crude intermediate from Step A in 4 mL of methanol was treated with 4 mL of 40% aqueous dimethylamine. After stirring at room temperature for 15 minutes, the reaction mixture was evaporated under vacuum and the residue dissolved in 4 mL of methanol and treated with 1 mL of 10% methanolic p-toluenesulfonic acid. After 15 minutes at room temperature, the reaction mixture was treated with saturated aqueous sodium bicarbonate. The mixture was diluted with water then extracted with methylene chloride. The organic layer was dried and evaporated under vacuum; the residue was purified by preparative thin layer chromatography on silica gel, eluting with hexane/ethyl acetate (2:1) to afford 133 mg of product.
