METHOD OF SYNTHESIS OF COMPOUNDS OF 5-(ALKOXY-METHYL)-2,3-PYRIDINE CARBOXAMIDE, INTERMEDIATE COMPOUNDS Russian patent published in 2002 - IPC

Abstract RU 2186771 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to a method of synthesis of compounds of the formula (I) by interaction of compound of the formula (II) with compound of the formula (III) and a base in the presence of a solvent at increased temperature. This method ensures to synthesize compounds of 5-(alkoxymethyl)-2,3-pyridine carboxamide of the more purity as compared with known ones. Also, the invention concerns an intermediate compound of the formula (IV) where X is halogen atom and R² means -C₁-C₆-alkyl. EFFECT: improved method of synthesis. 9 cl, 4 tbl, 3 sch, 22 ex
