Reaction Steps

Sodium hydride (60%) was added to a solution of 2-[6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl]-9-(2-trifluoromethylphenyl)-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a]azepine obtained in Examples 74 and 75 (83 mg) in DMF (5 mL) with stirring under ice-cooling until bubbling was stopped. Thereafter, the mixture was stirred at room temperature in an oxygen atmosphere. After four days, ice water, chloroform and a saturated sodium thiosulfate solution were added to the reaction solution, and the organic layer was separated. The organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was diluted with toluene and concentrated under reduced pressure. The residue was diluted again with toluene and concentrated under reduced pressure. The precipitated solid was collected by filtration, washed with chloroform and then air-dried to obtain 36.8 mg of the title compound. The property values of the compound are as follows.
