실험 절차

To a solution of 2-(methylsulfonyl)-5-[4-nitro-3-(tetrahydro-2H-pyran-4-yloxy)phenoxy]pyridine (25.8 g) in ethanol (250 mL) and tetrahydrofuran (250 mL) was added 10% palladium carbon (3 g), and the mixture was stirred under hydrogen pressure of 0.5 MPa at 50° C. for 6 hr. Palladium carbon was removed, and the mixture was concentrated under reduced pressure to give the title compound (24 g, yield 100%) as a white powder.
