Versuchsvorschrift

4-(4-Morpholinyl)benzonitrile (1.24 g, 6.6 mmol) in THF (25 mL) at 0° C. was treated with LiAlH4 (2.5 g, 65.9 mmol) and refluxed for 1 hour. The mixture was cooled to room temperature and quenched by careful addition of 1N NaOH and then H2O. The mixture was concentrated, extracted with diethyl ether. The combined ethereal extracts were washed with saturated NaHCO3 solution, dried over Na2SO4, and evaporated in vacuo to provide the title compound which was dried over MgSO4 as a THF:diethylether solution before the next step.
