Participants

Reaction Steps

To a solution of benzoic acid (51 mg, 0.402 mmol) in N,N-dimethylformamide (2 ml) was added 1,1′-carbonyldiimidazole (65.2 mg, 0.400 mmol). The mixture was stirred for 30 minutes at room temperature and then a solution of N5,1-dimethyl-N5-[2-({4-[(methylsulfonyl)methyl]phenyl}amino)pyrimidin-4-yl]-1H-benzimidazole-2,5-diamine (88 mg, 0.201 mmol) and triethylamine (0.03 ml, 0.201 mmol) in N,N-dimethylformamide (2 ml) was added. The reaction mixture was stirred for 16 h, quenched with saturated sodium bicarbonate solution (30 ml) and the product then precipitated. The crude product was filtered, washed with water, diethyl ether and air dried to give the desired product without further purification. 1H NMR (400 MHz, d6-DMSO) δ 12.82 (s, 1H), 9.28 (s, 1H), 8.28 (d, J=7.3 Hz, 2H), 7.89 (d, J=6.1 Hz, 1H), 7.74 (d, J=8.2 Hz, 2H), 7.59 (d, J=8.4 Hz, 1H), 7.51-7.44 (m, 4H), 7.25-7.20 (m, 3H), 5.79 (d, J=5.9 Hz, 1H), 4.34 (s, 2H), 3.77 (s, 3H), 3.47 (s, 3H), 2.84 (s, 3H). MS (ESI) m/z=542 [M+H]+.
