HCID 30160135-Methyl-2-nitrobenzoyl chloride

Procedure

A mixture of 5-methyl-2-nitrobenzoic acid (3.6 g, 19.87 mmol) and thionyl chloride (18 mL) was stirred under reflux for 20 hours then concentrated under reduced pressure to give 5-methyl-2-nitrobenzoyl chloride (3.77 g) which was used without further purification.

Workup

  1. temperatureunder reflux for 20 hours
  2. concentrationthen concentrated under reduced pressure
