Procedure

To a suspension of 4-amino-3-nitrobenzoic acid (1.64 g, 9 mmol) in THF (25 mL) was added diisopropylcarbodiimide (1.13 g, 9 mmol). The mixture was stirred at RT for 15 min and to the resulting yellow solution was added hydrazine (600 mg, 18 mmol). The resulting orange suspension was stirred at RT for 2 h. The solid was filtered and washed twice with THF to give the title compound: MS: m/z 195.1 (M−1).
