実験手順

To the mixture of [2-methyl-1-{[2-methyl-3-(trifluoromethyl)phenyl]methyl}-6-(4-morpholinyl)-1H-benzimidazol-4-yl]methanol, prepared as described in Example 43 (160 mg, 0.381 mmol) in N,N-Dimethylformamide (DMF) (15 mL), sodium hydride (30.5 mg, 0.763 mmol) was added in and followed by the addition of methyl iodide (0.048 mL, 0.763 mmol). The reaction was stirred at rt for 3 hours. More sodium hydride (30.5 mg, 0.763 mmol) and methyl iodide (0.048 mL, 0.763 mmol) was added in. The reaction was stirred at rt for another 2 hours then Water (70 mL) was added in. The mixture was extracted with EtOAc (100 mL). The organic phase was washed with Brine (100 mL), dried (MgSO4) and concentrated. The crude was subjected to ISCO purification (0˜2% MeOH/DCM) to give the product. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.36 (s, 3 H) 2.54 (s, 3 H) 3.00-3.07 (m, 4 H) 3.37 (s, 3 H) 3.68-3.75 (m, 4 H) 4.76 (s, 2 H) 5.52 (s, 2 H) 6.32 (d, J=7.83 Hz, 1 H) 6.88 (m, 2 H) 7.25 (s, 1 H) 7.60 (d, 1 H).
