실험 절차

To a mixture of 2.5 g of 40% aqueous methylamine solution and 30 ml of CH3CN was added dropwise 3.0 g of crude (6-fluoro-3-pyridyl)methyl bromide with constant stirring. The mixture was allowed to stand at room temperature overnight and concentrated under reduced pressure. The residue was extracted with AcOEt and the extract was dried over MgSO4 and concentrated. The procedure gave 1.35 g of the title compound as a crude orange-colored oil.
