Procedure
A mixture of rac-6-chloro-3-pyridin-3-yl-1,3-dihydro-indol-2-one (0.081 g, 0.33 mmol) (from Example 39b supra), 3-chlorobenzyl bromide (0.080 g, 0.39 mmol) (Aldrich), potassium iodide (0.065 g, 0.39 mmol) and potassium carbonate (0.098 g, 0.72 mmol) in acetone (3 mL) was heated at 67° C. for 2 hours in a capped pressure tube. After cooling, the 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 to give rac-6-chloro-3-(3-chloro-benzyl)-3-pyridin-3-yl-1,3-dihydro-indol-2-one as an off-white solid. (Yield, 0.05 g, 42%).
