Vorschrift

To a reaction mixture containing 3.6 gms (0.01 mol) of 2-{1-[(5-chlorothien-2-ylmethoxy)imino]butyl}-3-hydroxy-5,5-dimethylcyclohex-2-en-1-one and 0.87 gm (0.011 mol) of pyridine in 20 mls of methylene chloride stirred at 0° C. is added 0.89 gm (0.011 mol) of acetyl chloride. The mixture is then stirred at room temperature for 2 hours. The mixture is then worked up by washing with water, drying with anhydrous magnesium sulfate, and filtered. The filtrate is evaporated under vacuum affording 3-acetyloxy-2-{1-[(5-chlorothien-2-ylmethoxy)imino]butyl}-5,5-dimethylcyclohex-2-en-1-one.
