実験手順

16 mg of 5-bromo-2-trifluoromethyl-pyridine, 50 mg of cesium carbonate and 10 mg of copper(II) oxide were added to an N-methylpyrrolidinone (1 ml) solution of 21 mg of 5-(2-fluorophenoxy)-6-hydroxy-2-pyrazin-2-yl-1H-benzimidazole obtained in Example 251 (step 1), and the reaction liquid was stirred at 130° C. for 5 hours. The deposit was separated through filtration, and the solution was purified through reversed-phase middle-pressure liquid chromatography [ODS-AS-360-CC (by YMC), mobile phase: water-acetonitrile-0.1% trifluoroacetic acid]. The resulting fraction was diluted with ethyl acetate, washed with aqueous saturated sodium bicarbonate, and dried with anhydrous sodium sulfate. The solvent was evaporated away under reduced pressure to obtain the entitled compound as a brown solid.
