4-Pyridinepropaneamide → 4-Pyridinepropanenitrile

참여 물질

반응 단계

A mixture of 3-(4-pyridyl)-propionamide (7.1 g, 0.47M) in POCl3 (25 ml) was heated at about 100° to about 110° C. for 2 hrs. The excess of POCl3 was removed in vacuo from the reaction. Thereafter water was added and the resulting solution was basified with aqueous Na2CO3 sol. and extracted with CHCl3. The combined extracts were dried over Na2SO4 and concentrated and distilled at 1 mmHg/118°-120° C. to give 4(2-cyanoethyl)pyridine as an oil (4.8 g, 77% yield).
