Procedure

A solution containing ˜50% of propylphosphonic anhydride in N,N-dimethylformamide (Fluka, Buchs, Switzerland; 674 μL, ˜1.05 mmol) is added within 20 minutes to a stirred mixture of 4-methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-benzoic acid (214.4 mg, 0.7 mmol), N,N-diethyl-1,3-benzenediamine (115 mg, 0.7 mmol) and triethylamine (776 μL , 5.6 mmol) in 2 mL N,N-dimethylformamide. After stirring for 24 hours at room temperature, the mixture is treated with a half-saturated aqueous solution of sodium hydrogen carbonate 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 purified by chromatography on silica gel, eluent 2% methanol in dichloromethane and crystallised from acetone to give the title compound as a crystalline solid. 1H-NMR (400 MHz, DMSO-d6, δ): 1.07 (t, 6H); 2.31 (s, 3H); 3.29 (m, 4H); 6.38 (m, 1H); 7.06 (m, 2H); 7.11 (m, 1H); 7.36 (d, 1H); 7.43–7.50 (m, 2H); 7.67 (m, 1H); 8.21 (m, 1H); 8.43 (m, 1H); 8.51 (d, 1H); 8.66 (dd, 1H); 9.12 (s, 1H); 9.24 (m, 1H); 9.90 (s, 1H).
