Versuchsvorschrift

To anhydrous methanol (6.0 mL) at 0° C. under nitrogen was added sodium metal (˜1 g) and the mixture stirred for 30 minutes. To the reaction mixture was added 1-(6-fluoropyridin-2-yl)cyclobutanecarbonitrile (1.6 g, 9.1 mmol) followed by heating to 75° C. and stirring for 45 minutes. The solution was cooled to room temperature and partitioned between water and EtOAc. The layers were separated, the aqueous phase was extracted with EtOAc, and the combined organic phases were washed with saturated NaCl, dried over Na2SO4, and concentrated in vacuo to give the desired product (1.7 g, 97%) as a colorless oil.
