Versuchsvorschrift
The entire toluenic solution from Example 1 (420 ml) was admixed at 60° C. dropwise with 54.2 g (0.456 mol) of thionyl chloride and stirred at <60° C. for up to 22 h. Subsequently, the mixture was concentrated by distilling off 229 ml. The suspension was cooled to <20° C., and the product was isolated by filtration with suction, washed 3 times with 20 ml each time of toluene and dried at elevated temperature under reduced pressure.
