実験手順

4-(4-Methanesulfonyl-phenoxy)nitrobenzene (28 g, 95 mmol) prepared in Step B was dissolved in methanol (500 mL) and ethyl acetate (500 mL). 10% Pd/C (1.0 g) was added thereto, and the mixture was stirred under hydrogen gas of atmospheric pressure for 3 h. After completion of the reaction, the reaction mixture was filtered through a cellite, washed with methanol, concentrated under reduced pressure, and dried over anhydrous magnesium sulfate to give the title compound (25 g, Yield 100%).
