METHOD FOR PRODUCTION OF ACYL AMINOBENZAMIDE DERIVATIVES Russian patent published in 1995 - IPC

FIELD: organic chemistry. SUBSTANCE: compound having formula 2: R₁R₂NH and R₄ is used as reagent 1, compound having formula -CR₅R₆(CH₂X₁) is used as reagent 2. Their interaction is carried out in organic solvent in the presence of base or in excess of amine, the process is followed by isolation of desired product or by treatment if it is necessary thus prepared product where X₁-Cl R₃ and R₄ where is Cl, Br, I. Said treatment is carried out with the help of base or two-phase system which contains organic solvent and water in the presence of catalyst to produce compound where together with C(O)N form acetyl-2-on ring. EFFECT: improves efficiency of the method. 7 tbl
