Procedure

Ethyl p-cyclohexylphenylglyoxylate, 49.5 g. (0.19 mole) and 6.1 g. of iodine are dissolved in 100 ml. of carbon tetrachloride. To this solution is added a solution of 56.7 g. (0.8 mole) of chlorine dissolved in 500 ml. of carbon tetrachloride over a period of 3 hours. During the addition, the temperature of the reaction mixture is maintained at 0° C. The mixture is stirred for 3 hours and allowed to stand with gradual warming to room temperature over 30 hours. The solvent is removed in vacuo. The residue is fractionally distilled to obtain ethyl 3,5-dichloro-4-cyclohexylphenylglyoxylate.
