BuLi 1.6M in hexane (0.0316 mol) was added dropwise at −70° C. to a mixture of 6-bromo-4-(3-chlorophenyl)-2-methoxyquinoline (0.0287 mol) in TBIF (100 ml). The mixture was stirred at −70° C. for 30 minutes and a solution of 4-iodo-N-methoxy-N-methyl-benzamide (0.0244 mol) in THF (30 ml) was added. The mixture was stirred at −70° C. for 30 minutes, poured out into ice water and extracted with CH2Cl2. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated till dryness, yielding 15.6 g (>100%) of [4-(3-chlorophenyl)-2-methoxy-6-quinolinyl](4-iodophenyl)methanone, (intermediate 18).This product was used without further purification.
