4,4'-Bipyridine → HCID 21959970, compound

Participants

Reaction Steps

9.6 g of 3-phenyl-1-bromopropane were added dropwise over the course of 45 min to 15.0 g of 4,4′-bipyridyl in 90 ml of toluene at 70° C. The mixture was stirred for 24 h at reflux temperature, cooled down and the solid was filtered off with suction. The solid was stirred in 90 ml of toluene for 4 h at reflux temperature, cooled down, filtered off with suction and washed with toluene. Drying in vacuo gave 14.3 g (85% of theory) 4-(4-pyridyl)-1-(3-phenylpropyl)pyridinium bromide.
