Reaction Steps
The procedures of Examples 17 and 18 are repeated, except that in each case 137.5 parts of 5-hydroxyethylsulfonyl-2-nitrobenzoic acid and also the aqueous mother liquor and the Pd catalyst of the previous batch are used, to give in each case about 122 parts of 5-hydroxyethylsulfonylanthranilic acid of melting point 164° to 166° C. and a purity (diazotization) of >99%, that is, mother liquor and catalyst can each be used at least 10 times without deterioration of the product or decrease in yield.
