Abstract
PROCESS FOR THE PREPARATION OF NEW SULFONAMIDS, ESPECIALLY PROCEDURE FOR THE PREPARATION OF 6- (p-Aminobenzolsulfonamido) -pyrimidine of the general formula ** (See formula) ** where one of the radicals R1 and R2 represents a low-lower alkyl-alkoxy residue and the other a hydrogen atom, a halogen atom, a low alkyl radical, a low alkoxy radical, a low-alkyl lower alkoxy radical or a low alkoxy lower alkoxy radical, and its acyl derivatives, characterized in that a compound of formula ** (See formula) ** it is reacted with a compound of formula ** (See formula) ** where Y and Y1 are dissociable residues in the reaction leaving the imino group -NH- contained in one of them, Z the amine group or the substituent Z1 that allows the formation of the amine group and R1 and R2 have the indicated meaning, or in a compound of the formula ** (See formula) ** where Z has the indicated meaning and one of the residues R1 'and R2' represents a low alkoxy lower alkyl moiety and the other a transformable X moiety in a halogen atom, an alkoxy moiety or a low alkoxy alkoxy moiety, X is converted to a halogen atom, to an alkoxy radical, to a low alkoxy radical, and to the compounds obtained, which contain the radical Z 1, at the p-position of the benzene nucleus the amine group is formed and/or the bis-pZ-benzolesulfonyl compounds are dissociated to the mono-pZ-bensolsulfonyl compounds and/or, if desired, the compounds obtained are N1-acylated and/or in the obtained compounds, within the scope of the definition of the final materials, the substituents are modified or replaced by hydrogen and/or the free compounds obtained are transformed into their salts or the salts obtained in the free compounds.
