Reaction Steps
A solution of n-butyllithium (0.1 mol) in 65 ml of hexane is added to a mixture of 4"-propyl-2,3-difluoro-p-terphenyl (0.1 mol), potassium t-butylate (0.1 mol) and 200 ml of THF at -100° C. After stirring 5 minutes at -100° C. a mixture of brompentane (0.1 mol) and N,N-dimethylpropylene urea (0.1 mol, DMPU) is added. After warming-up to -30° C. and usual work-up 4"-propyl-4-pentyl-2,3-difluoro-p-terphenyl is obtained.
