Procedure
A solution of N-(2-dimethylaminoethyl)-N-(5-chloro-2-pyridyl)acetamide (45.5 g, 0.19 mole) in 200 ml of 6 N-hydrochloric acid is stirred at reflux for 16 hours. The excess hydrochloric acid is removed by evaporation under reduced pressure. The oily residue is treated with excess 10 N sodium hydroxide and the product is extracted into ether. The ether extract is dried, filtered and evaporated under reduced pressure. The residual oil is purified by distillation, b.p. 106°-111° at 0.7 mm n25D 1.556. Weight obtained is 32.5 g.
