実験手順: 37.6 g of 2,4,6-trimethyl phenol and 11 g of sodium hydroxide were dissolved in 30 ml of water and mixed with 150 ml of toluene. The toluene recovered from heating was mixed with 139 ml of N,N-dimethylformamide to obtain a N,N-dimethylformamide solution. 40 g of 2,6-dichlorophenol was dissolved in 130 ml of toluene, followed by the addition of 9.8 g of sodium hydroxide in 20 ml of water, 41.5 g of N-phenyl chloroacetamide and 8.7 ml of N,N-dimethylformamide, and refluxed in a oil bath at 140°-150° C. for 15 h. The toluene was recovered from the reflux, and mixed with the above N,N-dimethylformamide solution and reacted for 3 h. Recovering N,N-dimethylformamide from the reacted mixture with distillation under reduced pressure (145°-150° C., 8 mm Hg) resulted in the formation of 53 g of N-phenyl 2,6-dichloroaniline and the product yield was 90.75%.
