A method is proposed for the alkylation of pyrazoles with dichloroethane in water in the presence of the phase-transfer catalyst benzyltriethylammonium chloride (TEBAC). It was shown that dehydrochlorination of the corresponding N-(β-chloroethyl)pyrazoles in water under conditions of phase-transfer catalysis proceeds smoothly with the formation of N-vinylpyrazoles in 80-90% yield. 2005 Springer Science+Business Media, Inc.
