Versuchsvorschrift

A solution of 174 mg (0.66 mmol) of 5-(3,4,5-trimethoxyphenyl)penta-(2E,4E)-dienoic acid in anhydrous dimethylformamide-methylene chloride (0.1 ml-5 ml) was cooled in an ice bath, and to the solution was added 0.080 ml (0.92 mmol) of oxalyl chloride with stirring. The ice bath was removed, and the mixture was stirred for 30 minutes at room temperature. The reaction mixture was concentrated under reduced pressure to obtain crude crystals of 5-(3,4,5-trimethoxyphenyl)penta-(2E,4E)-dienoyl chloride.
