Procedure

Twelve grams of the above hydrochloride, 125 ml of methanol, 2 ml of concentrated hydrochloric acid, 10 ml of water, and 1 g of 10% palladium on carbon were shaken with hydrogen (50 psig initial pressure) for 24 hours. The mixture was diluted with 500 ml of methanol, heated to reflux and filtered. The filtrate was evaporated to dryness and the residue was slurried with ethanol and filtered. The solid was recrystallized from methanol to obtain 5.2 g of the title compound as the hydrochloride, m.p. 252°-5° C. dec.
