실험 절차
Thionyl chloride (30 ml) was added dropwise to a mixture of intermediate (19) (0.0245 mol) in DCM (150 ml), previously cooled on an ice bath. The mixture was stirred at a low temperature for 1 hour and at room temperature overnight. The solvent was evaporated till dryness. The product was used without further purification, yielding (quant.) of ethyl 4-(3-chlorophenyl)-6-[chloro(4-phenyl-2-thiazolyl)methyl]-1,2-dihydro-2-oxo-3-quinolinecarboxylate (intermediate 20).
