Reaction Steps

A mixture of rac-6-chloro-3-(3,4-dimethyl-phenyl)-1,3-dihydro-indol-2-one (0.18 g, 0.66 mmol) (from Example 52b supra), 3-chlorobenzyl bromide (0.16 g, 0.77 mmol) (Aldrich), potassium iodide (0.13 g, 0.78 mmol) and potassium carbonate (0.197 g, 1.42 mmol) in acetone (5 mL) was heated at 70° C. for 4 hours. After cooling, mixture was partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate three times. The combined organic layer was washed with water and brine, dried (Na2SO4), filtered and concentrated. Residue was purified by chromatography to give rac-6-chloro-3-(3-chloro-benzyl)-3-(3,4-dimethyl-phenyl)-1,3-dihydro-indol-2-one as yellow solid. (Yield 0.08 g, 30.8%).
