Production of 1-(6-Fluoromethyloxynaphthalen-2-yl)-2-methyl-1-(1-trityl-1H-imidazol-4-yl)-1-propanol 2-Bromo-6-fluoromethyloxynaphthalene (2.10 g) was dissolved in ether (100 ml), and the solution was cooled to −70° C. To the solution was slowly added a solution of n-butyllithium in hexane (1.6 M, 5.7 ml), and the mixture was stirred at −70° C. for 20 min. To the mixture was added dropwise a solution of 4-formyl-1-trityl-1H-imidazole (1.58 g) in THF (10 ml). The mixture was stirred for 20 min at −70° C. To the mixture was added water, and the mixture was extracted with ethyl acetate and dried. The solvent was distilled off and the residue was purified by silica gel chromatography (eluent, hexane:ethyl acetate=1:1) followed by recrystallization from diisopropyl ether to give the titled compound (1.73 g) as colorless needles.
