実験手順

6-Bromo-4-hydroxyquinolin-2(1H)-one (3.2 g, 18.3 mmol, Intermediate 44: step a), 6-(trifluoromethyl)nicotinaldehyde (4.0 g, 16.7 mmol), and diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (4.2 g, 16.7 mmol), in pyridine (34 mL) were heated to 105° C. for 3 hours. The solution was allowed to cool to ambient temperature, resulting in the formation of solid. Minimal isopropanol was added to the mixture and the slurry was stirred for 1 hour, sonicated, and filtered. The filtered solids were rinsed with isopropanol and dried under continuous air flow to provide the title compound as an off-white solid. Additional product was recrystallized from the filtrate, filtered, and rinsed with isopropanol.
