Procedure
A mixture of 2-(2-dimethylaminoethylamino)-4-methyl-6-chloropyridine (from Example 77, Part A) (21.4 g., 0.1 mole), liquid ammonia (85 g) and copper sulfate catalyst (1.0 g) in 150 ml. ethanol is heated at 200° C. for 48 hours in a pressure vessel. The cooled reaction mixture is filtered and concentrated in vacuo. The residual oil is dissolved in 125 ml of chloroform, washed with excess sodium hydroxide and then with saturated sodium chloride solution, dried, filtered and concentrated in vacuo. The 16.0 g. of crude oil obtained is taken up in 100 ml of ether, filtered and extracted into dilute hydrochoric acid. The acidic extract is made basic and the product is extracted into ether. After drying and removing the ether in vacuo, the product (8.0 g.) is distilled. Purified material is collected at 125°-128° C. at 0.4 mm.
