FIELD: organic synthesis. SUBSTANCE: safe and efficient method (without separately preparing alpha-halomethyl ethers and without their utilization) for attaching alkoxymethyl group to nuclear nitrogen atom of a wide range of pyrrole compounds is proposed involving interaction of corresponding pyrrole precursor successively with dialkoxymethane, Wilsmeyer reagent, and tertiary amine. Products can be used as insecticides, acaricides, nematocides, and limacides. EFFECT: increased yield and considerably reduced environmental pollution. 10 cl, 4 ex
