Procedure

A mixture of rac-6-chloro-3-cyclohexyl-1,3-dihydro-indol-2-one (0.11 g, 0.44 mmol) (from Example 19b supra), 3-chlorobenzyl bromide (0.11 g, 0.53 mmol) (Aldrich), potassium iodide (87 mg, 0.53 mmol) and potassium carbonate (0.13 g, 0.95 mmol) in acetone (3 mL) was heated at 60° C. for 2 days in a capped pressure tube. After cooling, mixture was diluted with ethyl acetate and extracted with water and brine. Aqueous layers were back washed with ethyl acetate. Organic layers were combined, dried (Na2SO4), filtered and concentrated. The residue was purified by chromatography (ethyl acetate-dichloromethane, 5:95, V/V) to give rac-6-chloro-3-(3-chloro-benzyl)-3-cyclohexyl-1,3-dihydro-indol-2-one as a white solid. (Yield 30 mg, 18%).
