The residue was dissolved in methylene chlorideand washed with water. The methylene chloride was concentrated and the residual oil was dissolved in 20 ml. of boiling acetonitrile, filtered, cooled, and treated with hydrogen chloride/methanol with cooling to give 0.22 g. of the desired product (m.p. 163°-166° C.).
