| abstract | METHOD OF OBTAINING 4- OR 5-ALKILMERCAPTOETHYLFURAN-2-CARBIC ACIDS OF GENERAL FORMULA (I) X O COOH where X is a group, R is lower alkyl with Y is a hydrogen atom, or X is methyl with Y is a -CHj-S-CH group , by the interaction of alkyl chloromethyl ester of furan-2-carboxylic acid with the sodium salt of a sulfur-containing derivative in an organic solvent followed by alkaline hydrolysis of the resulting product during boiling, characterized in that, in order to simplify the technology and expand the range of target products, as an alkyl ester Chloromethyl-substituted furan-2-carboxylic acid uses a compound of the general formula (tj) Ja R, O eoOR, where R has the indicated values, R is chloromethyl at Rj is a hydrogen atom, or R is methyl at clormethyl, as the sodium salt is serosoder-. The derivative is used (L0, L-dialkyldithiophosphate sodium of the general formula (III). $ - h1 e f. RO cd c, where R has the indicated values, as the organic solvent is used (the alcohol of the general formula. (IV) - ROH, where R has the indicated values, and the reaction of the compound of the general formula (II) with the compound of the general formula (III) is carried out at room temperature, followed by hydrolysis of the resulting product directly in the reaction mixture npii mass ratio of alcohol and water from 83:15 to 95: 5 . |
