Product 1

HCID 1196812-Cyanobenzoyl chloride

Procedure

A mixture of 2-cyanobenzoic acid (2 g, 13.6 mmol) and 15 ml of thionyl chloride was refluxed overnight. Excess thionyl chloride was removed in vacuo and the resultant 2-cyanobenzoyl chloride obtained as such as an off white solid was used in the above acylation.

Workup

  1. temperaturewas refluxed overnight
  2. customExcess thionyl chloride was removed in vacuo
