実験手順
2-Amino-4-(2-furyl)thiazole (330 mg, 1.99 mmol) obtained in Step 1 was suspended in chloroform (4 mL), and N-bromosuccinimide (360 mg, 2.02 mmol) was added thereto, followed by stirring at room temperature for 1 hour. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure to afford the entitled Compound g (438 mg, 90%).
