229 g (1.04 mol) of 8-chloro-1,2,3,4,5,6-hexahydrobenzo[f]quinoline were dissolved in 2 ml of methylene chloride, treated with 115 g (1.14 mol) of triethylamine, and 89.5 g (1.14 mol) of acetyl chloride in 400 ml of methylene chloride were added dropwise thereto at 0°. After stirring at room temperature for 1 hour, the mixture was poured into water, extracted with methylene chloride, and the methylene chloride phase was dried with magnesium sulphate. Distillation of the solvent in vacuo gave a crude product which was suspended in 500 ml of ether and filtered off. There was obtained 4-acetyl-8-chloro-1,2,3,4,5,6-hexahydrobenzo[f]quinoline of melting point 106°-108°. Concentration of the mother liquor and chromatography (silica gel/chloroform) gave a further portion of melting point 106°-108°.
