Potassium Cyanide → 4-Amino-6-(methyl-phenyl-amino)-[1,3,5]triazine-2-carbonitrile

Participants

Reaction Steps

To a stirring solution of 6-chloro-N-methyl-N-phenyl-[1,3,5]triazine-2,4-diamine (Intermediate 41, 360 mg, 2.67 mmol) in DMF (25 ml) was added potassium cyanide (435 mg, 6.68 mmol). The reaction was stirred at 120 C under nitrogen for 2 h. The reaction mixture was diluted with EtOAc (80 ml); the solution was then extracted with 5% aq. sodium hydrogencarbonate solution (2×20 mL), and saturated brine (2×5 mL). After evaporation of the solvent, the crude residue was purified by FCC over silica gel eluting with heptane:EtOAc 1:0 to 8:2 to 6:4 to furnish the desired product (380 mg, 63%). Method C HPLC-MS: MH+ requires m/z=227. Found: m/z=227, Rt=1.24 min (95%).
