실험 절차

A suspension of 300 g of 4-chlorocinnamic acid (J. Am. Chem. Soc., 89:3803, 1967) and 25 ml of concentrated sulfuric acid in 1.7 liters of methanol is heated to reflux for 24 hours. The solution is concentrated, and filtered to give as a white solid, p-chlorocinnamic acid methyl ester, mp 74°-5° C.
