In one non-limiting reaction scheme, dinitrobenzoic acid may be reacted with about one to about five equivalents of an alkali hydrosulfide in a methanol:water mixture at reflux temperature for about 20 to about 40 minutes to produce an aminonitrobenzoic acid. As is described in the Example below, 2,6-dinitrobenzoic acid may be allowed to react with about three equivalents of sodium hydrosulfide in a methanol:water mixture at reflux temperature for about 30 minutes to produce 2-amino-6-nitrobenzoic acid. In some non-limiting embodiments, three equivalents of sodium hydrosulfide may be reacted with one equivalent of the sodium salt of 2,6-dinitrobenzoic acid in refluxing methanol/water followed by acidification.
