Methanol → [1-(2-Phenylethylsulfonyl)piperidin-4-yl]methanamine

Participants

Reaction Steps

A mixture of [1-(2-phenyl-ethenesulfonyl)-piperidin-4-ylmethyl]-carbamic acid benzyl ester (2.5 g), 20% palladium hydroxide (1 g) on carbon, 200 mL of methanol and 50 mL of tetrahydrofuran were shaken under 50 psi of hydrogen for 2 days at room temperature. The catalyst was filtered off and washed with 250 mL of methanol. Concentration under reduced pressure gave C-[1-(2-phenyl-ethanesulfonyl)-piperidin-4-yl]-methylamine as white solid.
