3-Bromopyridine (0.92 ml) was dissolved in ether (20 ml), and the solution was cooled at −78° C. To the solution was slowly added dropwise a solution of n-butyllithium in hexane (1.6 M 5.9 ml), the mixture was stirred for 20 min at −78° C. To the reaction mixture was slowly added a solution of (6-methoxynaphthalen-2-yl)-(1-trityl-1H-imidazol-4-yl)ketone (1.0 g) in THF (8 ml), and the mixture was stirred for 30 min at −78° C. To the reaction mixture was added water, and mixture was diluted with 2% citric acid (50 ml). The dilution was extracted with ethyl acetate, washed with saturated aqueous solution of sodium chloride, dried and concentrated. The residue was recrystallized from a mixed solution of ethyl acetate and diethyl ether to give the titled compound (0.98 g) as a pale yellow powder.
