실험 절차
To a suspension of 1-[1-(2-hydroxyphenyl)vinyl]imidazole (500 mg) and triethylamine (407 mg) in dry methylene chloride (5 ml) is added trityl chloride (1.12 g) under stirring at room temperature, and the mixture is stirred at room temperature for 1 hour. To the mixture ice water is added and extracted with methylene chloride. The methylene chloride extract is dried on anhydrous sodium sulfate, and then concentrated. The residue is chromatographed on a column of silica gel, and eluted with methylene chloride-methanol (3-5%). The eluate is concentrated and the residue is crystallized from isopropyl ether and a small amount of petroleum ether to give 1-[1-(2-trityloxyphenyl)vinyl]imidazole (525 mg). mp. 149°-144° C.
