実験手順

A mixture of 6-chloro-2-ethyl-1-[4-(2-hydroxyethyl)phenyl]-1H-benzimidazole-5-carboxamide (Example 111, step 4, 500 mg, 1.45 mmol), triethylamine (293 mg, 2.90 mmol) and methanesulfonyl chloride (322 mg, 2.9 mmol) in dichloromethane (20 ml) was stirred at room temperature for 6 h. The reaction mixture was poured into water, and extracted with dichloromethane (50 ml). The organic layer was washed with brine (50 ml), then dried (Na2SO4). After removal of solvent, the crude product was purified by TLC with hexane/ethyl acetate (1:1) to afford 304 mg (50%) of the title compound as white solids.
