Versuchsvorschrift
To a mixture of 2.8 g (0.0162 mol) of cis-3-(acetylthio)propenoic acid and 0.1 ml of N,N-dimethylformamide in 50 ml of toluene under nitrogen was added 2.84 ml (0.0325 mol) of oxalyl chloride. After 3 h the solvents were removed to give cis-3-(acetylthio)propenoyl chloride. This crude product was used in the next step without any further purification.
