Participants

Reaction Steps

A solution of 2,5-di(2-cyanoethyl)pyridine from Step C (3.16 g) was dissolved in 7N ammonia in methanol solution (45 mL) and hydrogenated under 40 psi of hydrogen gas pressure at 50° C. in the presence of Raney nickel (1.6 g) for 20 h. The catalyst was filtered through solka floc® and washed with methanol. The filtrate and wash were combined and concentrated under reduced pressure to give 2,5-di(3-aminopropyl)pyridine (I)(2.95 g).
