実験手順

A solution of (E)-N-methyl-2-(2-phenoxyphenyl)-2-methoxyiminoacetamide (500 mg) in dichloromethane was cooled to 0° C., and sulfuryl chloride (285 mg) was dropwise added thereto. The resultant mixture was stirred at the same temperature for 2 hours, diluted with water and extracted with diethyl ether. The solvent was dried and removed, and the residue was subjected to HPLC with a mixture of hexane and ethyl acetate to give 382 mg of the objective compound.
