FIELD: organic chemistry, medicine, pharmacy.
SUBSTANCE: invention relates to novel compounds of the formula (I) 
or their pharmaceutically acceptable salts or solvates possessing properties of modulator of activity of insulin-like growth factor-1 (IGF-1) receptors, their synthesis and using. These compounds can be used in cancer treatment also. In the general formula (I) R1 represents a 5- or 6-membered heteroaromatic ring comprising at least one ring heteroatom chosen from nitrogen, oxygen or sulfur atom and wherein this ring is optionally substituted with at least a substitute chosen from (C1-C6)-alkyl, (C1-C6)-alkoxy-group (each can be optionally substituted with at least one substitute chosen from halogen atom, hydroxyl and trifluoromethyl group), halogen atom, cyano-group, hydroxyl, (C1-C6)-alkoxycarbonyl, -C(O)NR7N8, and unsaturated 5-6-membered ring that can comprise at least one heteroatom chosen from nitrogen atom, and wherein this ring is optionally substituted with at least one substitute chosen from (C1-C6)-alkyl, (C1-C6)-alkoxy-group (each can be optionally substituted with at least one substitute chosen from halogen atom, hydroxyl and trifluoromethyl group), halogen atom and cyano-group; R2 represents (C1-C4)-alkyl group; R3 represents hydrogen atom or halogen atom; R4 represents 5-membered heteroaromatic ring comprising at least one ring heteroatom chosen from nitrogen atom, and wherein this ring is optionally substituted with at least one substitute chosen from (C1-C6)-alkyl, (C1-C6)-alkoxy-group (each can be optionally substituted with at least one substitute chosen from halogen atom, hydroxyl and trifluoromethyl group),(C3-C6)-cycloalkyl; each R7 and R8 represents independently hydrogen atom, or R7 and R8 in common with nitrogen atom to which they are bound form 4-6-membered saturated heterocycle.
EFFECT: improved method of synthesis and preparing, valuable medicinal properties of compounds and pharmaceutical composition.
