Reaction Steps

To a mixture of 8-[(3,4-difluorobenzyl)oxy]-3-[3-methoxy-4-(2-methyl-1,3-oxazol-5-yl)phenyl]-N-(2,2,2-trifluoroethyl)-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridine-8-carboxamide (200 mg) in DMF (5 mL) were added cesium carbonate (169 mg) and methyl iodide (0.026 mL) at room temperature. After stirring at room temperature for 2 hr, the reaction mixture was poured into water, and the mixture was extracted with ethyl acetate/THF (2/1). The extract was washed with brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (75 mg).
