Versuchsvorschrift

To a stirred solution of 1-(6-methoxypyridin-2-yl)cyclobutanecarbonitrile (1.7 g, 8.8 mmol, 1.0 equiv) in THF (20 mL) was added lithium aluminum hydride solution (1.0 M in THF, 11 mL, 11 mmol, 1.1 equiv). The mixture was refluxed for 1.5 hours and allowed to cool to room temperature. Water (0.43 mL) was added slowly followed by 0.43 mL of 3 M NaOH and then three additions of 0.43 mL of water (Fieser and Fieser workup). The resulting mixture was filtered through diatomaceous earth and rinsed with THF. The combined organics were dried over Na2SO4 and concentrated to dryness to give the desired product (1.6 g, 97%) as a viscous oil.
