Methylamine → 3-(Methylaminomethyl)pyridine

To 25 ml of a 20% aqueous solution of NAOH stirred under cooling with ice-water, a 40% aqueous solution of methylamine (13.6 g, 0.175 mole) was added dropwise over 5 minutes, followed by further dropwise addition of an aqueous solution (10 ml) of 8.2 g (0.05 mole) of 3-pyridylmethyl chloride hydrochloride over 10 minutes. The mixture was further stirred at room temperature for 2 hours and, then, extracted with CH2Cl2 (100 ml×3). The extract was dried over MgSO4 and distilled to remove the solvent. The residue was subjected to vacuum distillation to give 2.6 g of the title compound as a yellow oil.
