N-(2-Amino-4-chlorophenyl)-6-chloronicotinamide (282 mg, 1 mmol) and 5 ml of ethylenediamine were heated to 80° C. for 3 hours. The excess ethylenediamine was removed under vacuum. To the residue was added 5 ml of 0.20 M NaOH. The mixture was extracted with 100 ml of ethyl acetate. The ethyl acetate was removed under vacuum to give the title compound (180 mg, 59% yield) as a brown solid. LC-MS (m/z) 306 (M+1).
