실험 절차
To a solution of 4-methyltetrahydro-2H-pyran-4-carbonitrile (1.8 g, 14.38 mmol) in THF (30 mL) was added carefully 1M LAH/THF (21.57 mL, 21.57 mmol) at 0° C. The reaction mixture was stirred for 15 min at 0° C., allowed to warm to ambient temperature and stirred for ˜3 hours at ambient temperature. To the reaction mixture was carefully added water (0.9 mL), 1N aqueous NaOH (2.7 mL) and water (0.9 mL) [Caution: gas development!]. The mixture was vigorously stirred for 30 min. The precipitate was filtered off and rinsed with THF. The solution was concentrated in vacuo providing crude (4-methyltetrahydro-2H-pyran-4-yl)methanamine as a yellowish solid, which was directly used in the next step without further purification. Yield: 1.54 g. LCMS (m/z): 130.1 [M+H]+; Retention time=0.21 min.
