4-Fluorobenzonitrile → 4-(6-(1-acetyl-pyrrolidin-2-yl)-2-pyridin-2-yl-1-(2-trimethylsilanyl-ethoxymethyl)-1H-benzimidazol-5-yloxy)-benzonitrile

Reaction Steps

5.8 mg of sodium hydride was added to an N-methyl-pyrrolidinone (1 ml) solution of 30 mg of 1-(2-(6-hydroxy-2-pyridin-2-yl-3-(2-trimethylsilanyl-ethoxymethyl)-3H-benzimidazol-5-yl)-pyrrolidin-1-yl)-ethanone obtained in Example 121 (step 10) and 20 mg of 4-fluorocyanobenzene, and the reaction liquid was stirred overnight in a sealed tube at 100° C. After cooled, aqueous saturated sodium bicarbonate was added to the reaction liquid, then this was extracted with ethyl acetate, the organic layer was washed with water, and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through partitioning thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (by Merck), chloroform/methanol=9/1) to obtain the entitled compound as a yellow oily substance.
