FIELD: chemistry.
SUBSTANCE: invention refers to the methods of warfare irritants disposal, namely to the liquidation and disposal of 2-chloro-1-phenylethanone-1 (chloracetophenone). The method is implemented by the cyclocondensation of 2-chloro-1-phenylethanone-1 with 1-dicyan-2-(2-chlorophenyl)-ethylene in presence of catalytic amounts of piperidine. After filtering, washing and recrystallisation from ethylic alcohol the resulting product - 2-phenyl-3-chloro-4(2-chlorophenyl)-5-cyan-6-amino-1,4-pyran is obtained.
EFFECT: disposal of 2-chloro-1-phenylethanone-1 by its transforming to 2-phenyl-3-chloro-4(2-chlorophenyl)-5-cyan-6-amino-1,4-pyran used in fine organic synthesis, chemistry of physiologically active substances and pharmaceuticals.
