Reaction Steps

Diethylcyanophosphonate (Aldrich, Buchs, Switzerland; 0.50 mL, 3.0 mmol) is added to a stirred mixture of 3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-benzoic acid (438 mg, 1.5 mmol), 4-[(4-methyl-1-piperazinyl)methyl]benzeneamine (308 mg, 1.5 mmol) and triethylamine (840 μL, 3.0 mmol) in 10 mL N,N-dimethylformamide at 10° C. After stirring for 12 hours at 60° C., the mixture is treated with an aqueous solution of sodium hydrogen carbonate and extracted three times with ethyl acetate. The combined extracts are washed with water, and the solvent is evaporated off under reduced pressure to give a residue. The residue is resuspended in water and filtered to afford the crude product which is recrystallised from tetrahydrofuran-ethyl acetate to give N-[3-[[4-(3-Pyridinyl)-2-pyrimidinyl]amino]-N-[(4-methyl-1-piperazinyl)-methyl]benzamide as a crystalline solid, m.p. 220–224° C.
