Versuchsvorschrift

A solution of 6-(4-Chloro-benzoyl)-4-(3-chloro-phenyl)-1H-quinolin-2-one (3.10 g, 7.87 mmol), prepared according to the methods described in PCT international patent application publication number WO 97/21701 (published Jun. 19, 1997), in DMF (28 mL) was treated with cesium carbonate (2.56 g, 7.87 mmol) and (bromomethyl)cyclopropane (2.13 g, 15.7 mmol). The reaction mixture was stirred at room temperature for 12 hours, diluted with dichloromethane (25 mL), and washed with 1N HCl (2×10 mL) and brine (20 mL). The combined organic extracts were dried (MgSO4), filtered, and concentrated in vacuo to give a black residue. Purification by flash column chromatography (silica, ethyl acetate:petroleum ether 1:9-3:7) gave 6-(4-Chloro-benzoyl)-4-(3-chloro-phenyl)-1-cyclopropylmethyl-1H-quinolin-2-one (2.39 g, 68%) as an off-white foam.
