Versuchsvorschrift
Piperidine (31.7 ml) and 4 -chloro-2 -picoline (13.65 g) were heated together in a bomb at 170 ° for 4.5 hours. After cooling, the mixture was taken up in water and extracted with ether. After drying (K2CO3) and stripping, the residue was distilled to give 4 -piperidino-2 -picoline, 15.45 g, b.p. 105°-10 ° (0.1 mm).
