4-(1,3-Dioxoisoindolin-2-yl)butanoyl chloride → 8-Chloro-1,2,3,4,5,6-hexahydro-4-(4-phthalimidobutyryl)benzo[f]quinoline

참여 물질

반응 단계

31.4 g (0.143 mol) of 8-chloro-1,2,3,4,5,6-hexahydrobenzo[f]quinoline dissolved in 300 ml of methylene chloride are added at 0° to a solution of 36.0 g (0.143 mol) of 4-phthalimidobutyryl chloride in 360 ml of methylene chloride and the mixture is stirred at room temperature for 1 hour. The solution is concentrated, extracted with methylene chloride and aqueous sodium hydrogen carbonate solution, dried with magnesium sulfate and the solvent is distilled in a vacuum. Extractive crystallization with acetone gives 8-chloro-1,2,3,4,5,6-hexahydro-4-(4-phthalimidobutyryl)benzo[f]quinoline as white crystals with melting point 182°-183°.
