FIELD: chemistry.
SUBSTANCE: invention relates to organosilicon chemistry and is a method of producing 1-(3-(trimethoxysilyl)propyl)benzimidazole, used for synthesis of immobilized ionic liquids, obtaining films on metal surfaces as an intermediate product in synthesis of biologically active compounds. Method is carried out in one reactor in two steps. At the first step, a sodium salt of benzimidazole is obtained by heating equimolar amounts of benzimidazole and sodium hydroxide in a toluene medium with water separation. Half of the used toluene is then distilled off, dimethylformamide is added to the reaction mass and the sodium salt of benzimidazole is alkylated with (3-chloropropyl)trimethoxysilane while heating for 3 hours at the boiling point of the reaction mass.
EFFECT: improved method of producing 1-(3-(trimethoxysilyl)propyl)benzimidazole using readily available starting reagents and a solvent which provides high output of the end product.
