Abstract
Process for obtaining new sulfonamides, especially for the preparation of N- (p-aminobenzolsulfonyl) -N-acyl-3-amino-2-phenyl-pyrazoles, unsubstituted in position 4 and 5, characterized in that 3- (pR -benzolsulfonamido) -2-phenyl-pyrazole, where R means the amino group or a moiety transformable therein by reduction, by methods already known N1 is acylated and in the obtained compounds, with a residue R transformable into an amino group, This is transformed into the free amino group.
