Reaction Steps

Compound g (10.0 g, 40.8 mmol) obtained in Reference Example 7 was dissolved in pyridine (136 mL), and under ice-cooling, 4-dimethylaminopyridine (250 mg, 2.04 mmol) and benzoyl chloride (8.05 mL, 69.4 mmol) were added thereto, followed by stirring at room temperature for 30 minutes. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (hexane:ethyl acetate=10:1) to afford N-[5-bromo-4-(2-furyl)thiazol-2-yl]benzamide (12.0 g, 84%) as a white solid.
