Procedure
2-Dimethylaminoethanol (34.8 g, 39.0 mmol) was treated with sodium (2.7 g, 11.7 mmol) in a sealed tube and stirred at ambient temperature until homogeneous. 4-Chloropyridin-2-amine (5 g, 3.9 mmol) was added and reaction heated to 150° C. and stirred in sealed tube for 8 hours. The mixture was cooled to ambient temperature before concentrating and triturating with dichloromethane (50 mL) four times. The combined triturates were concentrated and purified by column chromatography to give 4-(2-(dimethylamino)ethoxy)pyridin-2-amine as a yellow solid (3.8 g).
