실험 절차

In a microwave tube, 275 mg of 1-methyl-7-nitro-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one are introduced into 26 ml of methanol. 473 mg of ammonium formate and 398 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 give 250 mg of 7-amino-1-methyl-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in the form of a purple gum.
