Reaction Steps

A mixture of 1.38 g of (8aR)-2-[4-nitro-3-(propan-2-yloxy)phenyl]octahydropyrrolo[1,2-a]pyrazine, 2.72 g of hydrazine hydrate and 240 mg of 10% palladium-on-carbon (240 mg, 5 mol %) in 30 ml of ethanol is heated at 80° C. (bath) for 1 h 30. The mixture is filtered on Clarcel and the filtrate is concentrated under vacuum, so as to obtain 1.23 g of 4-[(8aR)-hexahydropyrrolo[1,2-a]pyrazin-2(1H)-yl]-2-(propan-2-yloxy)aniline in the form of a purple oil.
