The reaction mixture was partitioned between ethyl acetate and water. The resulting organic layer was washed with water, dried (over MgSO4) and evaporated. The resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system), and then the resulting product was converted into a hydrochloride in a conventional manner, to give the hydrochloride of the title compound as a pale yellow amorphous (255 mg, yield; 53%).
