Reaction Steps
{8-(3,4-Difluorobenzyl)-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-8-yl}methanol (100 mg) was added to a suspension of sodium hydride (60%, 9.4 mg) in DMF (1 mL) under ice-cooling, and the mixture was stirred for 30 min. Methyl iodide (14.7 μL) was added to the reaction mixture under ice-cooling. The reaction mixture was stirred under ice-cooling for 1 hr, and diluted with ethyl acetate, and the mixture was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (methanol/ethyl acetate) to give the title compound (80.0 mg).
