실험 절차

3,5-Dinitrobenzoic acid (5.30 g) was mixed with 40 ml polyphosphoric acid and heated to 64° C. o-Aminothiophenol (2.5 ml) was added and reaction maintained to 150° C. over 0.5 hr period. The mixture was quenched with 600 ml ice-water, neutralized with KOH, cooled, and filtered. The product yield was 3.20 g, mp 73.5°-84.5° C.
