In general, reaction of methyl 2-methoxy-4-acetylamino-5-nitrobenzoate with the base is preferably immediately followed by the in-situ reaction of the intermediate sodium-2-methoxy- 4-amino-5-nitrobenzoate (intermediate I) with hydrazine or its equivalent, preferably as hydrazine hydrate, to form 2-methoxy-4,5-diaminobenzoic acid (intermediate II). That product is preferably recovered and purified prior to further use.
