Procedure

A solution of dibenzyl N-((4[N,N-bis-(2-chloroethyl)amino]3-chlorophenylcarbamoyl))-L-glutamate (350 mg) in ethyl acetate (30 ml) containing 30% palladium on carbon 70 mg (50% moist) was stirred under an atmosphere of hydrogen for 1 hour. After filtration of the catalyst the filtrate was evaporated to dryness and the residue triturated vith ether/ethyl acetate to obtain N-(4-[N,N-bis(2-chloroethyl)amino]-3-chlorophenylcarbamoyl)-L glutamic acid as an oil. NMR: 8.7 (s) 1H; 7.6 (s) 1H; 7.1-7.4 (m) 2H; 6.5 (d) 1H; 4.2 (m) 1H; 3.3-3.6 (m) 8H: 1.7-2.4 (m) 4H.
