반응 단계
To a 500-mL, 3-necked round bottomed flask equipped with a thermocouple temperature monitor, nitrogen inlet and a magnetic stirrer was added 300 mL of ethyl vinyl ether and 25.0 g (0.29 mol) of methacrylic acid. The mixture was cooled in an ice bath and 0.2 g (0.001 mol) of p-toluenesulfonic acid monohydrate was added. The flask was removed from the ice bath and stirred for 4 hours at which time the mixture was filtered through a bed of sodium carbonate and the ethyl vinyl ether removed on a rotary evaporator. The resulting oil was distilled twice from sodium carbonate at reduced pressure to yield 8.9 g (20%) of the title compound as a clear, colorless oil.
