3-isopropoxy-N-(1-methyl-piperidin-4-yl)-4-nitro-benzamide → 4-amino-3-isopropoxy-N-(1-methyl-piperidin-4-yl)-benzamide

Participants

Reaction Steps

To a solution of 1.2 g (3.6 mmole) of 3-isopropoxy-N-(1-methyl-piperidin-4-yl)-4-nitro-benzamide in 25 mL of methanol was added 0.12 g of 10% palladium on carbon. The hydrogenation reaction was carried out under 50 psi of hydrogen for 2 hours. The mixture was filtered, concentrated under reduced pressure and triturated with ether. The solid was collected by filtration, washed with ether and dried under vacuum to give 1.0 g of 4-amino-3-isopropoxy-N-(1-methyl-piperidin-4-yl)-benzamide as a white solid.
