실험 절차

Ethylene glycol (3.10 g, 49.9 mmol) (Wako Pure Chemical Industries, Ltd.) and triphenylchloromethane (1.39 g, 49.9 mmol) (Wako Pure Chemical Industries, Ltd.) were dissolved in pyridine (6 mL) (Wako Pure Chemical Industries, Ltd.), and the solution was heated to 45° C. and stirred for 2 hours. Water (50 mL) was poured into the reaction solution, and mixture was extracted with toluene (Wako Pure Chemical Industries, Ltd.). The organic layer was dried with an hydrous sodium sulfate (Wako Pure Chemical Industries, Ltd.), and the solvent was distilled of funder reduced pressure. The residue was subjected to silica gel column chromatography (chloroform (Wako Pure Chemical Industries, Ltd.):methanol (Wako Pure Chemical Industries, Ltd.)=9:1), to thereby obtain the title compound (0.37 g, 24% yield).
