The solvent was removed in vacuo and the residue was partitioned between methylene chloride and dilute sodium hydroxide. The methylene chloride phase was dried over magnesium sulfate, and the solvent was removed in vacuo to give an oil. This was dissolved in methanol, an excess of ethereal hydrogen chloride was added and ether was added. A precipitate was collected to give 49.2 g (63.2%) of white crystalline solid, m.p. 169°-170° C.
