A mixture of 3-amino-4-phenoxy-5-sulphamyl-benzoic acid (3.08 g), allyl bromide (7.25 g), and dry ethanol was refluxed for 24 hours. After cooling, the precipitated ethyl-3-allylamino-4-phenoxy-5-sulphamyl-benzoate was filtered off and recrystallized from ethanol. The melting point of the ester was 153°-154° C.
