Reaction Steps
The procedure of previous Example 15 is repeated, except that the 3-hydroxyethylsulfonyl-2-nitrobenzoic acid is replaced by 2-hydroxyethylsulfonyl-3-nitrobenzoic acid and, after the clarifying filtration to remove iron sludge, a pH of 6.5 to 7.0 is established to give 64 parts of 2-hydroxyethylsulfonyl-3-aminobenzoic acid of the formula ##STR16## of melting point 75° to 77° C. and a purity (by diazotization) of 99.1%. Elemental analysis confirms the above structure.
