실험 절차

To a mixture of 7-chloro-2,3-dihydro-4(lH)-quinolinone (25 g), pyridine (32 g) and dioxane (200 ml) was added dropwise 2-ethylthio-3-pyridylcarbonyl chloride (37 under cooling at 0 C. to 5° C. with stirring. The mixture was allowed to react at room temperature for additional 3 hours. The reaction mixture was subjected to the procedure described in example 1, and 43 g of 7-chloro-l-(2-ethylthio-3-pyridylcarbonyl)-2,3-dihydro-4(lH)-quinolinone was obtained as white crystal.
