3-nitro-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide → 3-amino-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide

Participants

Reaction Steps

3-Nitro-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide (1.5 g, 3.2 mmol) was taken in a mixture of ethanol/methanol (50.0 mL/20.0 mL). This was added to a flask containing Pd/C (5 wt %) (0.15 g). The solution was evacuated and nitrogen purged and stirred under a balloon of hydrogen for 8 h. LC-MS indicated completion of reaction. Reaction was stopped, evacuated and nitrogen purged and filtered on celite. The solvent was rotavaped out to give 3-amino-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide (0.7 g, 47%).
