実験手順

Morpholine (7.0 g, 8.8 mmol) was added to the solution of 5-bromomethyl-2-chloro-pyridine in carbon tetrachloride (20 mL) and stirred at room temperature for 6 h. Water was added to the reaction mixture and the separated organic layer was washed with water, brine, dried over anhydrous sodium sulfate, filtered and concentrated to afford the crude product. Purification by column chromatography using silica gel (60-120 mesh) and ethyl acetate as eluent afforded 4-(6-chloro-pyridin-3-yl-methyl)-morpholine (1.2 g, 21%) as a brown oily liquid.
