Reaction Steps

A mixture of N-{[(2-{4-[2-(1-aminoethyl)-6-chloro-5-(trifluoromethyl)-1H-benzimidazol-1-yl]phenyl}ethyl)amino]carbonyl}-4-methylbenzenesulfonamide (step 3, 100 mg, 0.17 mmol) in CH2Cl2 (12 ml) was added acetyl chloride (0.01 ml, 0.18 nmmol) and stirred at room temperature for 5 h. The mixture was added water (10 ml) and extracted with CH2Cl2 (20 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/MeOH (10:1) to afford 59 mg (53%) of the title compound as white solids.
