Procedure

17.2 g of 2 -methoxy 4 -nitro 5 -chloroaniline dissolved in 150 ml benzene are added with 11.1 g of β chloropropionly chloride dissolved in 40 ml benzene and 2 ml pyridine. The reaction mixture is kept under stirring at room temperature for two hours then diluted with 250 ml water. The benzenic phase is separated while the aqueous phase is extracted twice with benzene. The benzenic solutions are united, washed with 2N hydrochloric acid then with water, dried on sodium sulphate, filtered and evaporated to dryness. The dry residue is recristallised from isopropyl ether and 21.1 g of 1(β chloropropionylamino) 2 -methoxy 4 -nitro 5 -chlorobenzene are recovered (yield 40-50%). It melts at 101°-110° (dec)
