Reaction Steps

A mixture of methyl 1-[(2,3-dichlorophenyl)methyl]-2-methyl-6-(4-morpholinyl)-1H-benzimidazole-4-carboxylate (65 mg, 0.15 mmol) and LiOH (19 mg, 0.5 mmol) in THF (5 mL) and water (5 mL), was stirred overnight at rt. Then the pH of the reaction mixture was neutralized with 1N aq. HCl. Then the mixture was stirred at rt for 1 h, filtered to give the product (47 mg, 74%, with about 10% monochloride as the impurity) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 2.53 (s, 3H), 3.12 (t, 4H, J=4.5 Hz), 3.73 (t, 4H, J=4.5 Hz), 5.66 (s, 2H), 6.42 (d, 1H, J=7.8 Hz), 7.26 (t, 1H, J=7.8 Hz), 7.42 (s, 1H), 7.48 (s, 1H), 7.62 (d, 1H, J=7.8 Hz); LC-MS: m/e=420 [M+1]+
