실험 절차
A solution of sulphuryl chloride (3.2 ml) in dichloromethane (20 ml) was added dropwise over a period of 10 minutes to the solution of 2'-acetyl-4'-fluoro-N-methylformanilide at 0° under a nitrogen atmosphere and the mixture stored overnight at 0 to 5°. Water (25 ml) was added whilst maintaining the temperature below 1 0°. The dichloromethane layer was separated, washed with water (1 25 ml) and dried over magnesium sulphate to give a solution of 2'-(2-chloroacetyl)-4'-fluoro-N-methylformanilide.
