HCID 14718889HCID 14718889, compound

Procedure

4-(Methoxymethyl)-2,3,5,6-tetrafluorobenzoic acid [5.0 g prepared by a process similar to that described in European Patent Application No. 54360] was dissolved in thionyl chloride (50 cm3) and heated to the reflux temperature with stirring for 3 hours. The excess thionyl chloride was evaporated under reduced pressure to yield 4-(methoxymethyl)-2,3,5,6-tetrafluorobenzoyl chloride (ca 5 g) as a pale yellow liquid.

Workup

  1. temperatureheated to the reflux temperature
  2. customThe excess thionyl chloride was evaporated under reduced pressure
