실험 절차
Under an atmosphere of hydrogen, a mixture of 1.9 g of the hydroxymethyl compound (prepared as described in Example 8), 1.0 g of 5% palladium on carbon and 12 ml of acetic acid was stirred at room temperature for 24 hours, and filtered. The filtrate was concentrated under reduced pressure. The residue was dissolved in water, neutralized with sodium bicarbonate, extracted with diethyl ether, and the extract was concentrated under reduced pressure. After addition of 6 N hydrochloric acid to the residue, the solution was concentrated under reduced pressure. The residue was purified by recrystallization from ethanol-diethyl ether to give 0.204 g of the title compound having the following physical characteristics:
