Procedure

A mixture of 0.1 mol of trans-4-octylcyclohexanecarbonyl chloride (prepared from the carboxylic acid with oxalyl chloride in toluene) and 75 ml of methylene chloride is added to a mixture of 0.1 mol of 2,3-difluoro-4-cyanophenol (prepared according to Example 4), 0.12 mol of pyridine, 10 mmol of 4-N,N-dimethylaminopyridine and 250 ml of methylene chloride. After the mixture has been stirred at room temperature for 10 hours, it is washed with dilute hydrochloric acid, saturated sodium bicarbonate solution and water. Customary working up gives 4-(trans-4-octylcyclohexanecarbonyloxy)-2,3-difluorobenzonitrile.
