실험 절차

A 200 ml flask equipped with a stirrer, a thermometer and a dropping funnel was charged with 14.8 g (0.1 mol) of p-hydroxyethylstyrene, 150 ml of benzene and 10.1 g (0.1 mol) of triethylamine and cooled to 10° C. To the mixture was added dropwise with stirring 13.7 g (0.1 mol) of ethoxalyl chloride for one hour at 10° C. to precipitate a hydrochloride of triethylamine (white solid). After mixting at room temperature for 2 hours, 80 g of hexane was added to complete precipitation of the hydrochloride. The hydrochloride is removed by filteration and the resultant filtrate was condensed to obtain the aimed compound. The compound was identified by 1H NMR (360 Mz) and IR. ##STR7##
