FIELD: organic chemistry, medicine, pharmacy.
SUBSTANCE: invention relates to new derivatives of benzofuran of the formula (1): 
wherein R represents L; R1 represents 2-R2-5-R3-pyrrol-1-yl-carbonyl, -CON(C2H5)2, -CON(CH2C6H5)2, -CON[CO2C(CH3)2]2; L represents bromine atom (Br); R2 and R3 in each case and independently of one another represent alkyl comprising 1-6 carbon (C)-atoms, and to their salts also. These compounds are intermediate substances used in synthesis of medicinal preparations showing effect on the central nervous system, for example, 1-[4-(5-cyanoindole-3-yl)butyl]-4-carbamoylbenzofuran-5-yl)piperazine. Invention provides synthesis if new intermediate compounds allowing synthesis of medicinal preparations such as 1-[4-(5-cyanoindole-3-yl)butyl]-4-carbamoylbenzofuran-5-yl)piperazine by the available method.
EFFECT: improved method of synthesis, valuable medicinal properties of compounds.
