Versuchsvorschrift

Diethylamine hydrochloride (8.3 g) is mixed with 6 ml of 37% formalin at room temperature for 30 minutes whereupon 40 ml of acetic anhydride is added dropwise at 60°-70° C. with stirring. After about 1 hour 11.5 g of 6-methyl-1,2,3,4,7,8,9,10-octahydro-benzo[f]quinoline-3,10-dione is added, and the resulting mixture is kept at 60°-70° C. for 3 hours. The reaction mixture is then concentrated under reduced pressure. To the residue is added 200 ml of acetone, and the mixture is heated under reflux for 10 minutes and then allowed to stand at room temperature. The precipitated crystals are collected by filtration and recrystallized from ethanol to give 7.0 g of 9-diethylaminomethyl-6-methyl-1,2,3,4,7,8,9,10-octahydro-benzo[f]quinoline-3,10-dione hydrochloride as colorless needles, melting at 196°-197° C.
