Reaction Steps

In a microwave tube, 316 mg of 1-methyl-7-nitro-8-(propan-2-yloxy)-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one are introduced into 20 ml of methanol. 443 mg of ammonium formate and 363 mg of Pd/C (10%) are added. 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 obtain 280 mg of 7-amino-1-methyl-8-(propan-2-yloxy)-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in the form of a colourless gum.
