실험 절차

4-Methoxy-2-methylsulfenylaniline (1.5 g) and diethyl ethoxymethylenemalonate (1.9 g) were reacted in the same manner as in Experimental Example 1 to obtain 3-ethoxycarbonyl-6-methoxy-8-methylsulfenyl-4(1H)-quinolone (2.1 g). The compound (1.3 g) was subjected to hydrolysis and decarboxylation in the same manner as in Experimental Example 2 to obtain 6-methoxy-8-methylsulfenyl-4(1H)-quinolone (compound 30, 0.95 g).
