By replacing the crotonamide and the unsymmetrical-dimethylhydrazine employed in Example 38 by equimolar quantities of N-tert-butyl-3-(3-furfurylamino-4-chloro-5-methylsulfinylbenzoyloxy)crotonamide and unsymmetrical-diethylhydrazine respectively and then following substantially the same procedure described in Example 38 there is obtained 3-furfurylamino-4-chloro-5-methylsulfinylbenzoic acid 2,2-diethylhydrazide.
