Procedure

A solution of 15 g (0.06 mol) of 3-iodobenzoic acid in 100 ml of anhydrous dichloromethane is introduced into a round-bottomed flask, 13 ml (0.063 mol) of dicyclohexylamine are added and the mixture is stirred for one hour. 4.6 ml (0.063 mol) of thionyl chloride are then added and the mixture is stirred for one hour. The mixture is evaporated to dryness, the residue is taken up in anhydrous ethyl ether, the dicyclohexylamine salt is filtered off and the filtrate is evaporated. 17 g (100%) of the crude acid chloride are collected, which product will be used without further purification for the rest of the synthesis.
