Procedure

A 500 ml round bottom flask equipped with a reflux condenser, a mechanical stirrer , a thermometer, a dropping funnel and an efficient N2 blanket, is charged with 30.0 g (0.25 mole) of 4-vinylphenol, 21.8 g of pyridine and 300 ml of chloroform. The contents are then cooled down to 5 degrees C., and 25,3 g of vinyl chloroformate is added dropwise via the dropping funnel with constant stirring and the temperature maintained at degrees or below. The temperature is then allowed to rise to ambient temperature and the mixture stirred overnight. The reaction mixture is then passed through a silica gel column and dried over magnesium sulfate and filtered. After the solvent is removed under pressure, the named product is recovered.
