5-ACETYLPYRROLE-2-CARBOXYLIC ACID METHYL ETHER SYNTHESIS METHOD Russian patent published in 2010 - IPC C07D207/34

Abstract RU 2404162 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method for synthesis of 5-acetyl-2-pyrrole carboxylic acid methyl ether by reacting 2-acetylpyrrole with carbon tetrachloride and methanol in an autoclave in the presence of a iron-containing catalyst selected from a group comprising ferrocene (Fe(C₅H₅)₂), tris(2,4-pentanedionato)iron (Fe(acac)₃), iron bromide (FeBr₂), iron acetate (Fe(CH₃COO)₂) in molar ratio [catalyst]:[2-acetylpyrrole]:[CCl₄]:[methanol]=1:100:375-1500:3250-9750, at temperature 80-95°C for 3-6 hours.

EFFECT: obtaining the desired product.
