Versuchsvorschrift

9.9 PARTS OF CYCLOHEXYLAMINE IS DISSOLVED IN 100 PARTS OF BENZENE AND THE MIXTURE IS REACTED WITH 15.5 PARTS OF 2-METHYLBENZOYL CHLORIDE IN THE PRESENCE OF 12 PARTS OF TRIETHYLAMINE AT 10°C. The whole is stirred for 3 hours at 60°C and then cooled; the precipitated triethylamine chloride is filtered, the filtrate is concentrated under vacuum and the residue is recrystallized from a mixture of methanol and water.
