Procedure

3-Methoxymethoxy-4-pyridin-4-yl-benzonitrile (122 mg, 0.51 mmol) is dissolved in ether (10 mL). The resulting solution is slowly added to a suspension of LiAlH4 (100 mg, 2.6 mmol) in Et2O. After addition, the mixture is stirred for another 10 min before quenched with H2O and 5 N NaOH. After which, EtOAc is added and the organic layer is collected and washed with brine and dried over Na2SO4. Removal of the solvent provided the crude amine, which is used directly in the next step. MS (ESI): 245 (M+1)+1.
