To the suspension of 2-methyl-6-(4-morpholinyl)-1-(1-naphthalenylmethyl)-1H-benzimidazole-4-carbonitrile (120 mg, 0.314 mmol) in n-butanol (15 mL) was added in acetic hydrazide (232 mg, 3.14 mmol) and potassium carbonate (434 mg, 3.14 mmol). The reaction was stirred at reflux temperature for 4 days. DCM (50 mL) and water (50 mL) were added in. The organic phase was washed with Brine (50 mL×3), dried (MgSO4), and the solvent was removed. The crude was purified by reverse phase purification to provide the desired product (36 mg, 25%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.71 (br. s., 3H), 1.78 (br. s., 3H), 2.21-2.37 (m, 4H), 2.90-3.08 (m, 4H), 5.20 (s, 2H), 5.74 (d, J=7.33 Hz, 1H), 6.17 (br. s., 1H), 6.51 (t, J=7.71 Hz, 1H), 6.75-6.95 (m, 3H), 7.04 (d, J=8.08 Hz, 1H), 7.17 (d, J=8.08 Hz, 1H), 7.43 (d, 1H). MS (ES+) m/e 439.1[M+H]+.
