Participants

Reaction Steps

A mixture of (±)-6-[(4-chlorophenyl)-1H-imidazol-1-ylmethyl]4-phenyl-2(1H)-quinolinone (0.022 mol) in phosphoryl chloride (100 ml) was stirred and refluxed for 2 hours. The mixture was evaporated in vacuo, the residue was taken up in CH2Cl2 and basified with K2CO3 (10%). The organic layer was dried (MgSO4), filtered off and evaporated. The product was used without further purification, yielding 8 g (85%) of (±)-2-chloro-6-[(4-chlorophenyl)-1H-imidazol-1-ylmethyl]-4-phenylquinoline (interm. 5).
