Versuchsvorschrift
148.0 g (755 mmol) of anhydrous sodium phenolsulfonate and 190.0 g (755 mmol) of γ-phthalimidobutanoyl chloride are reacted in 200 g of xylene at 140° C. for 4 hours and the mixture is worked up as in Example 1. The crude product is recrystallized from methanol and the white crystalline product is dried at 40° C. under a water pump vacuum.
