Reaction Steps
A mixture of methyl 4-bromo-2-chloro-1-(3-chloropropyl)-1H-benzimidazole-7-carboxylate (429 mg, 1.17 mmol), 4-methoxy-2-methylaniline (0.301 mL, 2.34 mmol) and p-toluenesulfonic acid monohydrate (0.0223, 0.117 mmol) in o-xylene (2.4 mL) was stirred at 120° C. for 3 days, and diluted with aqueous sodium bicarbonate. The resultant mixture was extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on NH silica gel eluting with a 10-40% ethyl acetate/n-hexane gradient mixture to give the title compound as a brown solid (301 mg, 0.700 mmol, 60%).
