Reaction Steps

To a suspension of 6-chlorooxindole (0.94 g, 5.34 mmol) (Cresent Chem.) in N,N-dimethylformamide (20 mL) at room temperature was added lithium hydride (86 mg, 10.7 mmol) (Aldrich). The mixture was stirred at room temperature for 10 minutes, then 6-chloro-2,4-dimethoxy-pyrimidine (0.93 g, 5.34 mmol) (Aldrich) was added. The reaction mixture was heated at 110° C. for 3 hours. The mixture was cooled to room temperature. Water (100 mL) was added, and mixture was extracted with ethyl acetate (2×100 mL). The organic layers were separated, combined, washed with water, brine, dried over Na2SO4 and concentrated. The residue was purified by chromatography (ethyl acetate) to give rac-6-chloro-3-(2,6-dimethoxy-pyrimidin-4-yl)-1,3-dihydro-indol-2-one as a brown solid. (Yield 0.23 g, 14%).
