(1R,2R)-N-tert-Butoxycarbonyl-2-benzyloxycyclohexylamine → (1R,2R)-trans-N-Boc-2-Aminocyclohexanol

Participants

Reaction Steps

A solution of 3.0 g of (1R,2R)-N-tert-butoxycarbonyl-2-benzyloxycyclohexylamine in 100 mL of methanol was combined with 300 mg of 5% palladium on carbon, and hydrogenated at room temperature under atmospheric pressure. After 48 hours, palladium on carbon was filtered off, and the filtrate was concentrated. The residue was subjected to chromatography on silica gel (n-hexane:ethyl acetate 2:1) to obtain 2.0 g of the desirable compound.
