The mixture was evaporated to an oil under reduced pressure, dissolved in hydrochloric acid (2 M) and extracted with toluene. After basifying the aqueous acid with sodium hydroxide (5 M) the basic oil was extracted with toluene and dried (MgSO4). The solvent was removed under reduced pressure to leave the title compound as an oil (27.7 g). The hydrochloride was formed in isopropyl alcohol-ethereal hydrogen chloride, m.p. 155°-156° C.
