Reaction Steps

A mixture of intermediate 4 (0.16 mol) in phosphoryl chloride (500ml) was stirred and refluxed for one night. The mixture was evaporated till dryness, the residue was taken up in ice and water, alkalized with NH4OH and extracted with DCM. The organic layer was decanted, dried (MgSO4), filtered off and evaporated, yielding 56 g (100%) of 6-bromo-2-chloro-4-(3-chlorophenyl)quinoline, mp.125° C. (intermediate 5).
