4-(1-t-Butoxycarbonylpiperidin-4-yloxy)-3-isopropylnitrobenzene → 4-(1-t-Butoxycarbonylpiperidin-4-yloxy)-3-isopropylaniline

Participants

Reaction Steps

To a solution of 4-(1-t-butoxycarbonylpiperidin-4-yloxy)-3-isopropylnitrobenzene (4.1 g) in methanol (70 ml) was added palladium on carbon (0.4 g) and the mixture was stirred under a hydrogen atmosphere at room temperature for 3 hours. The reaction mixture was filtered and the filtrate concentrated in vacuo. The residue was purified by chromatography on a silica gel column using hexane/ethyl acetate=3/2 as an eluant to give the desired compound (2.8 g, yield 74%) as a red oil.
