Reaction Conditions

Reaction Steps

696 mg of ammonium formate and 581 mg of Pd/C (10%) are added to a solution of 405 mg of 1-methyl-8-nitro-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in 39 ml of methanol. The reaction medium is microwave-heated at 80° C. for 5 minutes. The mixture is filtered on Clarcel, and the Clarcel is rinsed with methanol. The filtrate is concentrated under reduced pressure, so as to give 422 mg of 8-amino-1-methyl-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in the form of a colourless gum.
