실험 절차
7-Nitrobenzo[b]thiophene-1,1-dioxide (19 g, Example 17) was hydrogenated in 200 ml of ethyl acetate over 1.0 g of 10% palladium-on-charcoal catalyst at 500 pounds-per-square-inch of pressure and 100° C. until no more hydrogen gas was absorbed. The mixture was filtered through celite, and the filtrate was concentrated in vacuo. The solid residue was recrystallized from 1-chlorobutane to yield 13.2 g of the title compound; m.p. 117°-119° C.
