FIELD: chemistry.
SUBSTANCE: invention relates to organic chemistry, specifically to a method of producing 1-geranyl-2-methylbenzimidazole, involving allylation of 2-methylbenzimidazole. Disclosed method comprises first reacting myrcene with dialkylamine, such as dimethylamine, diethylamine, piperidine, morpholine, catalysed by sodium metal, followed by quaternisation of geranyl dialkylamine with ethyl- or methyl iodide and allylation of 2-methylbenzimidazole with formed geranyl trialkylammonium iodide in presence of sodium hydride and a palladium catalyst, to obtain desired 1-geranyl-2-methylbenzimidazole.
EFFECT: technical result is an environmentally friendly and technologically effective method of producing 1-geranyl-2-methylbenzimidazole.
