Procedure

2.1 Grams of 2-acetyl-5-[2-(4-trifluoromethylphenylthio)ethyl]cyclohexane-1,3-dione was dissolved in 10 ml of ethanol, and 0.71 g of ethoxyamine hydrochloride and 0.68 g of triethylamine were added to the resulting solution which was then stirred overnight at room temperature. The reaction solution was poured into water, acidified with dilute hydrochloric acid and extracted with chloroform. Chloroform was removed and the residue was purified by column chromatography on silica gel (eluent, ethyl acetate:hexane=1:5) to obtain 1.2 g of 2-(1-ethoxyaminoethylidene)-5-[2-(4-trifluoromethylphenylthio)ethyl]cyclohexane-1,3-dione as white crystals.
