Reaction Steps

To a mixture of 8-(3,4-dichlorophenyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridine (100 mg) in DMF (2 mL) was added sodium hydride (60%, 9.4 mg) at room temperature, and the mixture was stirred for 30 min in the air. The reaction mixture was diluted with water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (40.3 mg).
