Participants

Reaction Steps

The hydrochloride from above (10 g), 500 ml of methanol, 25 ml of water, 5 ml of concentrated hydrochloric acid and 0.5 g of 10% palladium on carbon were shaken with hydrogen (45 psig initial pressure) for 4 hours. The catalyst was separated and the solution was evaporated to dryness. The residue was dissolved in ethyl acetate and shaken with dilute sodium hydroxide solution. The ethyl acetate solution was dried over magnesium sulfate, then evaporated to dryness. The residue was dissolved in methanol and saturated with hydrogen chloride. The solution was evaporated to dryness. The residue crystallized on standing with ethyl acetate for 3 days. The solid was treated with boiling ethyl acetate and filtered to obtain the title compound as the hydrochloride, m.p. 228°-231° C. dec.
