Reaction Steps

2.2 g (5.8 mmol) of 1,4-dibenzyl-[1,4]-diazepan-6-carboxylic acid diethylamide are dissolved in 50 ml of ethanol and hydrogenated over 2 h at room temperature and normal pressure in the presence of 0.5 g of 10% palladium on activated charcoal. Filtration over kieselguhr gives an almost colorless filtrate from which [1,4]-diazepan-6-carboxylic acid diethylamide is obtained in the form of a light yellow oil by concentration under vacuum.
