Abstract
A process for producing heterocyclic compounds which are useful as pesticides, drugs, fungicidal materials or intermediates thereof. TosMIC is reacted with an aldehyde or an imino compound: 1) in a solvent mixture of an aprotic solvent with a protic solvent in the presence of a base, 2) in the presence of a phase-transfer catalyst and an inorganic base, or 3) in the presence of an inorganic base. Thus, a desired product can be efficiently obtained using a solution without isolating TosMIC which is irritating and unstable, has a low decomposition point and shows explosivity.
