Participants

Reaction Steps

A solution containing ˜50% of propylphosphonic anhydride in N,N-dimethylformamide (Fluka, Buchs, Switzerland; 875 μL, ˜1.5 mmol) is added within 20 minutes to a stirred mixture of 4-methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-benzoic acid (306 mg, 1.0 mmol), 4-[(4-methyl-1-piperazinyl)methyl]benzeneamine (Chem. Abstr. Reg. Number: 70261-82-4; 205 mg, 1.0 mmol) and triethylamine (830 μL, 6.0 mmol) in 8 mL N,N-dimethylformamide. After stirring for 24 hours at room temperature, the mixture is treated with a saturated aqueous ammonium chloride and extracted three times with ethyl acetate. The solvent is evaporated off under reduced pressure and the residue dried in vacuo. The crude product is crystallised from ethanol-ethyl acetate to give the title compound as a crystalline solid, m.p. 153-155° C.
