FIELD: organic chemistry. SUBSTANCE: invention describes compounds of the formula (I): where substituents and symbols have values given in the invention claim and designated for control of Helicobacter bacterium. Indicated new compounds are synthesized either interaction of compound of the formula (II) with compound of the formula (III) or interaction of compound of the formula (IV) with compound of the formula (V) H[[Y-C r H 2r ] t -[Z-C u H 2u ] v -R4 (V). Synthesized compounds are oxidized and/or converted to salts and/or obtained salts are converted to free compounds if necessary. EFFECT: improved method of synthesis. 7 cl, 21 tbl, 5 dwg, 43 ex |
