Procedure

The catalyst was added to a solution of 406 mg of DL cis 7-p-nitrophenylacetamido-3-isopropyl-3cepheme-4-carboxylic acid in 3.8 ml of dimethylformamide and 1.12 ml of N hydrochloric acid and a current of hydrogen was passed therethrough until saturated. The mixture was filtered and the filter was washed with a 50--50 water-ethanol solution containing a few drops of hydrochloric acid. The filtrate was evaporated to dryness and the residue was taken up in 3 ml of water. Ammonium formate was added thereto to a pH of 4.5 and the mixture was stirred 5 minutes and vacuum filtered. The precipitate was empasted with water and dried to obtain DL cis 7-p-aminophenylacetamido-3-isopropyl-3-cepheme-4-carboxylic acid melting at 150°C with decomposition. The product occurred as ocre crystals slightly soluble in water, ethanol and chloroform and insoluble in ether.
