Abstract
Improvements introduced in the object of main patent no. 396,862, applied for on November 10, 1971 by: "A process for the preparation of new pyridine derivatives" according to which for the preparation of 4-phenylaminopyridine derivatives of the general formula: **(See formula)** wherein R1 represents an alcohol group containing 1 to 4 carbon atoms, while R2, R3, R4, R5 and R6 represent hydrogen or a methyl, nitro, trifluoromethyl or chlorine group, with the proviso that at least one of the symbols R2, R3, R4, R5 and R6 does not represent hydrogen, and if the number of substituents other than hydrogen represented by R2, R3, R4 R5 and R6 does not exceed two, the procedure is that a 3-sulfonamido -4-phenylaminopyridine of the formula **(See formula)** wherein R2, R3, R4, R5 and R6 have the meanings given above, is acylated with a chloride to carboxylic acid anhydride containing 2 to 5 carbon atoms, in the presence of pyridine, or a 4-chloropyridin-5- acylsulfonamide of the formula **(See formula)** wherein R1 represents an alcohol radical containing from 1 to 4 carbon atoms, is condensed with a substituted aromatic amine of the formula **(See formula)** wherein R2; R3; R4; R5 and R6 have the meanings given above, in the presence of copper powder.
