1,3-Propanediamine → N-(2-amino-4-fluorophenyl)-6-(3-aminopropylamino)nicotinamide

Participants

Reaction Steps

N-(2-amino-4-fluorophenyl)-6-chloronicotinamide (266 mg, 1 mmol) and 6 ml of 1,3-propanediamine were heated to 80° C. for 3 hours. The excess 1,3-propanediamine 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, 52% yield) as a brown solid. LC-MS (m/z) 304 (M+1).
