실험 절차

The whole of the 2-benzyloxybenzyl alcohol thus obtained was dissolved in 500 ml of tetrahydrofuran, and 85 ml of thionyl chloride were added dropwise, whilst ice-cooling, to the resulting solution. The reaction mixture was then allowed to stand overnight at room temperature, after which it was concentrated by evaporation under reduced pressure to give a dark colored oil. This product was dissolved in toluene, and the solution was decolorized by treating it with silica gel for chromatography followed by filtration. The filtrate was concentrated by evaporation under reduced pressure to give 2-benzyloxybenzyl chloride as a yellow oil, which was used in the following reaction without further purification.
