Procedure

A solution of N-[({2-[4-(5-acetyl-2-ethyl-1H-benzimidazol-1-yl)phenyl]ethyl}amino)carbonyl]-4-methylbenzenesulfonamide (Example 78, 100 mg, 0.19 mmol) in tetrahydrfurane (15 ml) was added MeMgI (1.2 ml, 0.99 mmol) dropwise under nitrogen at 0° C. The mixture was stirred at 0° C. for 1 h and then was stirred at rt for 30 min. The mixture was added water (10 ml) and extracted with CH2Cl2(50 ml). The organic layer was washed with brine (10 ml), then dried (Na2SO4). After removal of solvent, the crude product was purified by flash column chromatography eluting with CH2Cl2:methanol (30:1/20:1/10:1) to afford 100 mg (97%) of the title compound as white solids.
