Reaction Steps
A mixture of 83 mg (0.287 mmol) of 2-chloro-7-(3,5-diethyl-1H-pyrazol-1-yl)-1-methyl-1H-benzimidazole, 186 mg (0.862 mmol) of 4-bromo-2-methoxy-6-methylaniline and 0.15 mL of 1-methyl-2-pyrrolidinone was stirred at 110° C. for 20 hours. After cooling, the reaction mixture was neutralized with saturated aqueous sodium hydrogen carbonate, followed by addition of ethyl acetate. The resulting crystals were collected by filtration and washed with water and ethyl acetate to give 112 mg (83%) of the title compound.
