Participants

Reaction Steps

A suspension of 3.98 g (17.5 mmol) of 7-nitro-2-methyl-1,2,3,4-tetrahydroisoquinoline hydrochloride and 0.4 g of 10% palladium on carbon in 200 ml of ethanol was hydrogenated at 50 psi for 2 h. The catalyst was filtered and washed with a small amount of water. The filtrate was concentrated yielding an aqueous solution. Absolute ethanol was added and evaporated driving off the excess water until a solid was produced. This solid was dissolved in hot ethanol (60 ml) and ether was added slowly to induce crystallization. The product was collect to give 3.38 g (97%) of the title compound as an off-white solid, m.p. 114-9° C.
