Reaction Steps
A mixture of 10 g. (72 mmoles) of 2-chloroisonicotinonitrile, 30 ml. of tetrahydrofuran, 100 ml. of toluene and 20 ml. (0.3 mole) of dimethylamine was placed in a steel bomb and heated at 190° C. for 4 hours. The bomb was cooled and the mixture removed and filtered. The residue, remaining after the filtrate was concentrated, was dissolved in water, which was subsequently extracted with ether (3×40 ml.). The combined extracts were dried and concentrated to the crude product. Recrystallization from petroleum ether gave 7.4 g. (69%) of the pure product, m.p. 63°-66° C.
