実験手順

To a solution of methyl 7-(4-fluorophenyl)-3-(2-hydroxy-2-methylpropyl)-2-oxo-2,3-dihydro-1H-benzimidazole-5-carboxylate (80.0 mg, 0.223 mmol) in MeOH (0.446 mL) was added sodium hydroxide (0.446 mL, 1M, 0.446 mmol). Reaction heated in the microwave at 100° C. for 15 min. More sodium hydroxide (0.446 mL, 1M, 0.446 mmol) added and heated an additional 20 min in the microwave at 100° C. HCl (0.446 mL, 2M in ether, 0.892 mmol) was added and the reaction mixture was concentrated to give the title compound with four equivalents of sodium chloride (128 mg): LC-MS [M+1]=345.3.
