Reaction Steps

To a solution of 8.1 parts of ethyl (2-benzoyl-4-chlorophenylazo)bromoacetate in 16 volume parts of ether is added 160 volume parts of concentrated aqueous ammonia. After stirring the mixture for 1 hour at room temperature, the ether layer is separated, washed with water and evaporated to remove the solvent. The crystalline residue is collected by filtration, washed with ethanol and dried. The procedure gives ethyl (2-benzoyl-4-chlorophenylazo)-aminoacetate. Recrystallization from ethanol gives yellowish orange needles melting at 126°-127°C.
