Reaction Steps

A mixture of rac-3-(3-methoxy-phenyl)-6-chloro-1,3-dihydro-indol-2-one (82 mg, 0.3 mmol) (from Example 6b supra), 4-bromomethyl-2,6-dichloro-pyridine (85.3 mg, 0.35 mmol) (Maybridge), potassium iodide (59.2 mg, 0.35 mmol) and potassium carbonate (89.2 mg, 0.645 mmol) in acetone (3 mL) was heated at 60° C. for 3 hours 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. Residue was recrystallized from dichloromethane-hexanes to give rac-6-chloro-3-(2,6-dichloro-pyridin-4-ylmethyl)-3-(3-methoxy-phenyl)-1,3-dihydro-indol-2-one as a light brown solid. (Yield 60 mg, 45%).
