실험 절차

A solution of 4-(methylsulfonyl)nitrobenzene (6.26 g, 31.1 mmol) in THF (200 mL) and ethanol (100 mL) was placed in a high pressure reaction vessel and to this solution was added 5% Pd/C (1.6 g). The vessel was shaken for 8 h under an atmosphere of hydrogen (60 psi). The solution was then filtered through diatomaceous earth, partially concentrated in vacuo, and diluted with diethyl ether. The resulting precipitate was filtered and dried in vacuo to give 4.84 g (91%) of a tan solid.
