FIELD: organic chemistry, chemical technology, pharmacy. SUBSTANCE: invention relates to the improved method of synthesis of a compound of the formula (III): where R1 means hydrogen atom or heteroarylaryl; R2 is a group taken among CH2-O-aralkyl, CH2-OCO-alkyl, CH2OCONH2, CH2- OCOPh, CH2-OCOO-alkyl; R3 means C3-alkyl; R4 means dichlorophenyl that involves an interaction of a compound of the formula (I): where R1, R2, R3 is determined above with a compound of the formula (II): R4-S- HaL where R4 is determined above and HaL means halogen atom and reaction is carried out in the presence of a base. The proposed method can be used in industrial synthesis of compounds of the formula (III) that can be used as an antiviral agent and an agent against HIV. EFFECT: improved method of synthesis, valuable antiviral properties. 4 cl, 2 tbl
