実験手順

1-(6-tert-Butyldimethylsilyloxy-2-naphthyl)-2-methyl-1-(1-trityl-1H-imidazol-4-yl)-1-propanol (35.0 g) was dissolved in THF (100 mL) and cooled to 0° C. A solution (1 M: 100 mL) of tetrabutylammonium fluoride in THF was added dropwise. The mixture was stirred at room temperature for 1 hr., and the solvent was evaporated and water was added to the residue. The resulting precipitate was collected by filtration, washed with ether and water and dried to give the title compound (28.3 g) as a colorless powder.
