Reaction Steps
A mixture of 8-(1H-1,2,4-triazol-1-yl)-6-(trifluoromethyl)imidazo[1,2-a]pyridine-3-carboxylic acid (80 mg), 3-oxa-6-azabicyclo[3.1.1]heptane 2,2,2-trifluoroacetate (75 mg), HATU (133 mg), triethylamine (150 μL) and anhydrous DMF (3 mL) was stirred at room temperature for 12 hr, saturated aqueous sodium bicarbonate solution was added thereto, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane), and the obtained solid was recrystallized from ethyl acetate/hexane to give the title compound (59 mg).
