Versuchsvorschrift
N-(2′,6′-Dichlorophenyl)-4-methylaniline (4.86 g) is reacted with chloroacetylchloride (3.92 g) at 90° C. for 2 h. After dilution with toluene, the mixture is washed with aqueous sodiumcarbonate twice, 40% aqu. sodium bisulfite and water. The organic phase is dried (MgSO4) and evaporated. The residue is recrystallised from ethanol (12 g) to obtain N-(2′,6′-Dichlorophenyl)-N-chloroacetyl (2.83 g), mp: 129.5-130° C.
