실험 절차

To a solution of 5-hydroxy-1-methylpyrazol-4-yl 3-(4,5-dihydroisoxazol-3-yl)-2-methyl-4-(methylsulfonyl)phenyl ketone (100 mg, 2.75×10−4 mol) in anhydrous tetrahydrofuran (5 mL) were added triethylamine (55 mg) and 96% S-ethyl chlorothiolformate (45 mg) at room temperature. After the reaction solution was stirred for 1 hour, 150 mL of ethyl acetate was added, and the solution was washed twice with a saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=6:4) to obtain the desired product (82 mg) as an oil.
