Reaction Steps

250 g of the acid from Example 2 were suspended in 670 ml of toluene and dissolved with 102.6 g of pyridine. 1546 g of thionyl chloride were added dropwise to the reaction mixture at 60° C. over the course of 1 hour. After a post-reaction time of 3 hours, the red-brown emulsion was cooled to 0° C., and the rust-brown crystals were filtered off. The solution which remained was evaporated under reduced pressure.
