Reaction Steps
A mixture of 3.54 g of 4-(2,3-dichlorophenyl-carbamoyl)-phenoxyacetic acid, 3.57 g of thionyl chloride and 30 ml of dioxane was stirred at a temperature of 80° C. for 4 hours. An excess amount of thionyl chloride and dissolved hydrochloric acid gas, sulfurous acid gas and dioxane were distilled off by a rotary evaporator to obtain 4-(2,3-dichlorophenyl-carbamoyl)-phenoxyacetyl chloride as the residue after distillation.
