2,3,6,7-Tetrahydro-1H,5H-benzo[ij]quinolizine Use and Manufacturing
66.5g (0.5mol) of tetrahydroquinoline and 400g of 1-bromo-3-chloropropane were heated in a 150-160℃ oil bath for 20 hours. After cooling, 50ml of concentrated hydrochloric acid and 500ml of water were added to steam distillation to remove excess 1- Bromo-3-chloropropane. Adjust the residue to alkaline with 40% sodium hydroxide and extract with ether. The ether extract is washed with water, dried with granular sodium hydroxide, distilled to remove the ether, and distilled under reduced pressure to collect the 105-110°C (0.133kPa) fraction to obtain 67-70g of jololidine.
Used in organic synthesis.
