実験手順

After oxalyl chloride (0.055 ml; 0.63 mmol) was added to a solution of (E,E)-5-(3,4,5-trimethoxyphenyl)-2,4-pentadienoic acid (116 mg; 0.44 mmol) in dimethylformamidemethylene chloride (0.1ml-5 ml) under ice cooling. The ice bath was removed, and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure to obtain crude crystals of (E,E)-5-(3,4,5-trimethoxyphenyl)-2,4-pentadienoyl chloride.
