Reaction Steps

[step 1] 6-Fluoropyridin-3-amine (600 mg, 5.35 mmol) was dissolved in dichloromethane (20 mL), triethylamine (1.49 mL, 10.7 mmol) and cyclobutanecarbonyl chloride (0.67 mL, 5.89 mmol) were added, and the mixture was stirred at room temperature overnight. Water was added to the mixture, and the mixture was extracted 3 times with ethyl acetate. The combined organic layers were dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. To the obtained residue was added diisopropyl ether and the precipitated crystals were collected by suction filtration to give N-(6-fluoropyridin-3-yl)cyclobutanecarboxamide (899 mg, 86%).
