Procedure

The hydrochloride from above (21.5 g), 500 ml of methanol, 5 ml of concentrated hydrochloric acid, 15 ml of water and 0.6 g of 10% palladium on carbon were shaken with hydrogen (50 psig initial pressure) for 20 hours. The catalyst was separated and the solution was evaporated to dryness in vacuo. The residue was slurried with diethyl ether and filtered. The solid was triturated with refluxing ethanol, filtered and dried to obtain 12 g of the title compound as the hydrochloride, m.p. 238°-240° C. dec.
