Procedure
A mixture of ethyl 2-(2,2,2-trichloroethoxycarbonylmethoxyimino)-3-oxobutyrate (20 g) and sulfuryl chloride (7.7 g) in acetic acid (20 ml) was stirred at 40° C. for 7 hours. After the reaction mixture was added to a mixture of water (100 ml) and methylene chloride (100 ml) with stirring, the separated organic layer was washed with 5% aqueous sodium bicarbonate and water, followed by drying over magnesium sulfate. Removal of the solvent gave ethyl 2-(2,2,2-trichloroethoxycarbonylmethoxyimino)-4-chloro-3-oxobutyrate (22 g).
