FIELD: chemistry.
SUBSTANCE: second amines are N-alkylated by cis-2,3-dichlormethyl-hem-dichlorcyclopropane in the presence of the phase transfer catalyst triethylbenzylammonium chloride at 75°C for 8 hours in the presence of the following components, wt %: diethylamine 4.7; cis-2,3-dichloromethyl-hem-dichlorcyclopropane 6.7; dimethylsulphoxide 87.8; triethylbenzyl ammonium chloride 0.26; potassium hydroxide 0.54; a dibutylamine reaction is carried out in the following proportions, wt %: dibutylamine 8; -2,3-dichloromethyl-hem-dichlorcyclopropane 6.45; dimethylsulphoxide 84.8; ammonium chloride 0.25; potassium hydroxide 0.5.
EFFECT: higher target product yield and higher quality.
