Versuchsvorschrift

4-Chloro-α-methylbenzylamine (15.6 g) and triethylamine (10.1 g) were dissolved in toluene (150 ml). With stirring, a solution of 1,2,2-trichloro-3,3-dimethylcyclopropanecarboxylic acid chloride (23.6 g) in toluene (30 ml) was added dropwise to the solution at 0° to 10° C. After the addition, the mixture was stirred at room temperature for 2 hours. The reaction mixture was poured into ice water, and the aqueous layer was extracted with toluene. The toluene layers were combined, washed with a 1% aqueous solution of hydrochloric acid, a 1% aqueous solution of sodium hydroxide and water in this order, and then dried over anhydrous sodium sulfate. Toluene was evaporated under reduced pressure to give the desired N-(4-chloro-α-methylbenzyl)-1,2,2-trichloro-3,3-dimethylcyclopropanecarboxamide (32 g) represented by the following formula as colorless crystals. mp. 138°-139° C. ##STR35##
