Abstract

A procedure for preparing 2-phenylaminopyridine derivatives of the formula: **(See formula)** wherein R1 represents an amino radical or an acylamino radical, R2, R3, R4, R5 and R6 each represent hydrogen or a chlorine, nitro, alcohol or trifluoromethyl group, which comprises reacting a 2-chloro-pyridin-3- sulfonamide or a 2-chloropyridin-3-N-acylsulfonamide of the formula: **(See formula)** wherein R1 has the meanings indicated above with a substituted aromatic amine of the formula: **(See formula)** where R2, R3, R4, and R5 have the meanings given above, in the presence of copper powder, by heating to temperatures of 150-200ºC, and as long as it is possible and desirable to form a salt by reaction with an inorganic or organic base.
