| abstract | Procedure for the preparation of 3-n-butylamino-4-phenoxy-5-sulfamoylbenzoic acids of the formula I ** (See formula) ** wherein R1 means an alcohol group with 1 to 6 carbon atoms that may be branched or once unsaturated, or an aralkohyl group with up to 9 carbon atoms or a 2- (3- or 4-) pyridylmethyl group, characterized in that a 3-n-butylamino-4-phenoxy-5-sulfamoylbenzoic acid derivative of the formula II is reacted ** (See formula) ** with an alcohol of the formula R1OH if R2 represents CH2-O-CH3 and R represents hydrogen; with formaldehyde in the presence of an alcohol of the formula R1OH if R and R2 represent hydrogen, and hydrogenating a compound of the formula II in the presence of a palladium catalyst if R2 represents CH2-OR1 and R represents a benzyl group which may have one or plus alcohol or alkoxy groups, halogen atoms or nitro groups in the phenyl radical.
