8.78 g (40 mmol) of 8-chloro-1,2,3,4,5,6-hexahydrobenzo[f]quinoline were dissolved in 88 ml of methylene chloride and 7.70 g (44 mmol) of 4-chlorobenzoyl chloride in 60 ml of methylene chloride were added dropwise thereto at 0°. After stirring at room temperature for 1 hour the mixture was extracted with water, dried with magnesium sulphate and the solvent was distilled off in vacuo. Chromatography (silica gel, chloroform-hexane, 2:1) and crystallization (chloroform-hexane) gave 8-chloro-4-(p-chlorobenzoyl)-1,2,3,4,5,6-hexahydrobenzo[f]quinoline as white crystals of melting point 189°-191°.
