A solution of 2-iodo-pyridine (commercially available) (307 mg, 1.5 mmol) in dichloromethane (20 mL) at room temperature was treated with ethyl magnesium bromide (0.50 mL, 1.5 mmol, 3M in ether) and allowed to react for 45 m. A solution quinolin-8-yl(1-trityl-1H-imidazol-5-yl)methanone, (Intermediate 13) (465 mg, 1.00 mmol) in dichloromethane was added via syringe at room temperature and the reaction mixture was then stirred at room temperature for 16 h. The mixture was quenched with water (20 mL) and a sat. solution of ammonium chloride (20 mL). The residue was isolated in a typical aqueous to give pyridin-2-yl(quinolin-8-yl)(1-trityl-1H-imidazol-5-yl)methanol, (Intermediate 14) (385 mg, crude).
