実験手順

To a solution of methyl 4′-[(1,1-dioxidotetrahydro-2H-thiopyran-4-yl)oxy]-2′,6′-dimethylbiphenyl-3-carboxylate (0.128 g, 0.33 mmol) in tetrahydrofuran (2 mL) was added lithium aluminum hydride (80%, 15.7 mg, 0.33 mmol) by small portions under ice-cooling, and the mixture was stirred at the same temperature for 1.5 hr. Sodium sulfate 10 hydrate (0.106 g, 0.33 mmol) was added by small portions to the reaction mixture, and the mixture was stirred at room temperature for 1 hr. The insoluble substance was filtered off through celite, and the filtrate was concentrated under reduced pressure to give the title compound (0.111 g, yield 93%) as a colorless amorphous powder.
