실험 절차

N-(2-Aminophenyl)-6-chloronicotinamide (248 mg, 1 mmol) and 7 ml of 1,4-butanediamine were heated to 80° C. for 3 hours. The excess 1,4-butanediamine 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 (158 mg, 53% yield) as a brown solid. LC-MS (m/z) 300 (M+1).
