Reaction Steps

A solution of the compound (1) (1.37 g, 4.26 mmol), 2-(dimethylamino)ethylchloride hydrochloride (1.84 g, 12.3 mmol) and tetrabutylammonium hydrogensulfate (145 mg, 0.43 mmol) in methylene chloride (8.5 ml) and 4N sodium hydroxide (8.5 ml) was stirred under nitrogen atmosphere at room temperature for about 60 hours. The reaction mixture was diluted with water, extracted with methylene chloride, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by column chromatography on silica gel to recover the compound (1) (60% recovery) and to give the title compound (2). Yield 0.45 g (30%).
