The process described in Example 1 was repeated, using a solution in toluene of dimethyl 3-(3-chlorophenoxy)-2-oximinopropylphosphonate in place of the solution in toluene of dimethyl 3-(3-chlorophenoxy)-2-semicarbazonopropylphosphonate, to give dimethyl 3-(3-chlorophenoxy)-2-oxopropylphosphonate, RF = 0.29 (ethyl acetate), RF = 0.58 (5% v/v methanol in methylene dichloride).
