実験手順

2-Acetyl-5-ethoxy-4-metoxyaniline (550 mg), cyclopropylcarbonyl chloride (410 mg) and triethylamine (530 mg) were reacted in the same manner as in the preparation of compound 95 to give N-cyclopropylcarbonyl-2-acetyl-5-ethoxy-4-methoxyaniline (740 mg). The compound (600 mg) and potassium t-butoxide (1.18 g) were reacted in the same manner as in the preparation of compound 95 to obtain 2-cyclopropyl-7-ethoxy-6-methoxy-4(1H)-quinolone (compound 98, 330 mg).
