Reaction Conditions

Reaction Steps

A mixture of 2-acetylamino-4-chloro-5-nitrobenzoic acid (10.0 g) and 40% aqueous methylamine solution (60 ml) is stirred at 80° C. for 10 hours and then evaporated under reduced pressure. To the residue is added 40% aqueous methylamine solution (100 ml), and the resulting solution is stirred at 80° C. for 20 hours. After cooling, the mixture is diluted with water (50 ml) and then adjusted to the pH of about 4 with acetic acid. The precipitate is collected and recrystallized from acetonitrile to give the title compound (7.6 g), mp 260°-272° C.
