Reaction Steps

A mixture of 6-chloro-3-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one (0.16 g, 0.6 mmol) (from Example 6b supra), 3-chlorobenzyl bromide (0.15 g, 0.7 mmol)(Aldrich), potassium iodide (0.12 g, 0.71 mmol) and potassium carbonate (0.18 g, 1.3 mmol) in acetone (5 mL) was heated at 60° C. for 4 hours in a capped pressure tube. After cooling, mixture was diluted with ethyl acetate (50 mL) and extracted with water (2×50 mL) and brine (50 mL). Aqueous layers were back washed with ethyl acetate (50 mL). Organic layers were combined, dried (MgSO4), filtered and concentrated. Residue was recrystallized from dichloromethane-hexanes to give rac-6-chloro-3-(3-chloro-benzyl)-3-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one as white needles. (Yield 0.18 g, 75.3%).
