실험 절차

A mixture of 8.8 g of 2,4-dichloro-benzoylacetonitrile, 69.2 g of methyl o-formate and 10.5 g of acetic anhydride is refluxed at a bath temperature of 150° C. for 3 hours. The volatile constituents are then distilled off in vacuo and finally under a fine vacuum at a bath temperature of 120° C. 11 g of 2-(2,4-dichloro-benzoyl)-3-methoxy-acrylonitrile are obtained as a viscous oil.
