PURPOSE:To produce the titled compound useful as a raw material of pharmaceuticals, agricultural chemicals, etc., by reacting halogen with a vinyl ether available easily at a low cost, and contacting the reaction product with an alcohol. CONSTITUTION:A vinyl ether is made to react with a halogen (preferably chlorine or bromine) in a solvent such as hexane, chloroform, etc. at <=80 deg.C, especially at -10-+30 deg.C. The amount of the halogen is preferably 1-10mol per 1mol of the vinyl ether. The reaction product is made to contact with an alcohol to obtain the objective compound. The vinyl ether used as a raw material is represented by the formula R<1>OCH=CH-Y (R<1> is 1-8C alkyl such as methyl, n- octyl, etc.; Y is CN, etc.). The alcohol is the compound of formula R<3>OH wherein R<3> is preferably the same alkyl group as the R<1> of the vinyl ether.
