A 10-ml flask was charged with sodium 2,2,2-trichloro-1-(2,2-dimethyl-3-methoxycarbonylcyclopropyl)ethyl carbonate (compound 4, 0.73 mmol) and phosphorus trichloride (0.80 mmol) and stirred at 40° C. for 45 min. Then, the excess of phosphorus trichloride was removed at sub-atmospheric pressure. The conversion of compound 4 was at least 92%, with a selectivity to the title compound of at least 79%.
