with dichloro sulfoxide in toluene;Reflux;
Steps:
The preparation of 4,4-difluorocyclohexanecarbonyl chloride (8)
To the solution of 4,4-difluorocyclohexanecarboxylic acid (3 g, 18.3 mmol, 1 Eq.) dissolved in 7.5 ml toluene SOCl2 (6.6 ml, 5 Eq.) was added. The mixture was refluxed and stirred for 2-3 h. TLC showed the acid was consumed up, cooled, concentrated to yield about 2.5 g dryness oil (100% yield).
