Participants

Reaction Steps

2-Amino-4-(2-furyl)-5-(morpholinomethyl)thiazole (225 mg, 0.85 mmol) obtained in Step 1 was dissolved in DMF (4 mL), and nicotinoyl chloride hydrochloride (302 mg, 1.70 mmol) and triethylamine (0.24 mL, 1.70 mmol) were added thereto, followed by stirring at room temperature for 4 hours. A saturated aqueous solution of sodium hydrogencarbonate 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=1:1) to afford the entitled Compound 94 (73.0 mg, 23%).
