Reaction Steps

4-Methoxy-2-methylaniline (3.0 g) and diethyl ethoxymethylenemalonate (5.7 g) were reacted in the same manner as in Experimental Example 1 to obtain 3-ethoxycarbonyl-6-methoxy-8-methyl-4(1H)-quinolone (3.4 g). The compound (2.0 g) was subjected to hydrolysis and decarboxylation in the same manner as in Experimental Example 2 to obtain 6-methoxy-8-methyl-4(1H)-quinolone (compound 20, 0.7 g).
