Versuchsvorschrift

A solution of 11-bromoundecanoic acid (10.00 g, 37.7 mmol) dissolved in CH2Cl2 (30 mL) was slowly added to a solution of SOCl2 (7.0 mL, 94.0 mmol) in CH2Cl2 (25 mL). The mixture was refluxed for 5 h, then concentrated in vacuo to give 11-bromoundecanoyl chloride, which was used without further purification:
