Thionyl Chloride → 4-Acetoxy-3-fluorobenzoyl chloride

Participants

Reaction Steps

2.90 ml of thionyl chloride was added to 2.50 g (12.6 mM) of 4-acetoxy-3-fluorobenzoic acid. Under stirring at room temperature, two drops of N,N-dimethylformamide (DMF) was added thereto, followed by refluxing for 40 minutes. After the reaction, dry benzene was added to the reaction mixture, followed by two times of distilling-off of excessive thionyl chloride under reduced pressure to obtain 4-acetoxy-3-fluorobenzoyl chloride.
