실험 절차

In a 500 mL, round bottomed flask, (4-chlorophenyl)[2-(4H-1,2,4-triazol-3-yl)-3-thienyl]methanone (16.89 g, 58.29 mmol) was dissolved in tetrahydrofuran (500.0 mL, 6164 mmol). To the solution were added dihydropyran (31.9 mL, 3.50E2 mmol) and p-toluenesulfonic acid monohydrate (16.6 g, 87.4 mmol). The mixture was stirred for 3 h at rt. The reaction was quenched by the addition of saturated aqueous solution of sodium bicarbonate (200 mL). The aqueous phase was separated and then extracted with EtOAc (300 mL). The combined organic phases were dried over anhydrous sodium sulfate. The drying agent was removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by chromatography to afford (4-chlorophenyl)(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl)thiophen-3-yl)methanone as an oil which was dried under high vacuum overnight (19.4, 89.1%). LCMS: (FA) ES+ 374.2, 376.1.
