Ethanol → 2-[(Phenylsulfonyl)methyl]-6-(4-methylpiperazin-1-yl)-pyridin-3-ylamine

Participants

Reaction Steps

A mixture of 1-methyl-4-{5-nitro-6-[(phenylsulfonyl)methyl]pyridin-2-yl}-piperazine (1.60 g, 4.35 mmol) and 10% Pd/C (200 mg) in a 1:1 mixture of ethanol:THF is hydrogenated at 45 psi for 4 h at ambient temperatures. The catalyst is filtered off and the filtrate is concentrated in vacuo to afford the title compound as a yellow solid, 1.45 g (99% yield), identified by NMR analysis.
