Versuchsvorschrift

A solution of sulphuryl chloride (20.6 ml) in dichloromethane (30 ml) was added dropwise over a period of 45 minutes to the solution of 2'-acetyl-5'-fluoro-N-methylformanilide whilst maintaining the temperature below 2° with ice/water cooling under a nitrogen atmosphere. The mixture was stirred for 3 hours maintaining the temperature below 2°. Water (80 ml) was added dropwise over 15 minutes maintaining the temperature below 10°. The dichloromethane layer was separated and dried over magnesium sulphate to give a solution of 2'-(2-chloroacetyl)-5'-fluoro-N-methylformanilide.
