Abstract
A procedure for the preparation of sulfanilamide compounds of the formula: **(See formula)** where R1 represents hydrogen or R2 and each group R2 independently represents C1-C4 lower alkyl, lower alkenyl lower alkynyl or a radical of formula -CH2-CH2- (CH2) nY, where n represents 0 or 1 and Y represents methoxy, cyano, bromine or chlorine, with the limitation that the groups represented by R1 and R2 together contain from 2 to 8 carbon atoms, inclusive; and R3 represents hydrogen or methyl and each group R4, taken independently represents propyl or both groups R4, together, together with the nitrogen atom constitute an aziridine, pyrrolidine piperidine, hexahydroazepine, morpholine or piperazine ring, or one of these rings with a lower monoalkyl or lower dialkyl substituent of a total of not more than 3 carbon atoms; whose procedure is characterized by reacting a sulfanilamide compound of the formula: **(See formula)** and an amine of formula **(See formula)** in the presence of formaldehyde or paraformaldehyde.
