Procedure

290 mg (1.02 mmol) 4-(2-carboxymethoxy-ethylamino)-3-nitro-benzoic acid in 100 ml dichloromethane are combined with 0.186 ml (2.55 mmol) thionyl chloride and 2 drops of DMF and refluxed for one day. After evaporation of the solution i. vac. it is evaporated with toluene and the residue is further reacted without any more purification.
