Reaction Steps

To a slurry of [3-(2-oxo-1,2-dihydro-indol-3-ylidene)-1,3-dihydro-isobenzofuran-1-yl]-acetic acid (100 mg, 0.32 mmol) in THF (4.0 ml) at room temperature was added 2.5M n-BuLi in hexane (13611), and the reaction was stirred for 10 minutes. After the reaction was cooled to 0° C., oxalyl chloride (163 μl, 0.32 mmol) was added. After stirring for 20 minutes, 4-(2-hydroxyethyl)morpholine (118 μl, 0.976 mmol) was added. The reaction was stirred for 5 minutes at 0° C., and then at room temperature for 20 minutes. The reaction was partitioned between EtOAc and saturated NaHCO3. The EtOAc layer was washed with brine, dried with anhydrous Na2SO4 and rotary evaporated to afford an orange oil. The orange oil was chromatographed through silica gel column, eluted with CHCl3, to give [3-(2-oxo-1,2-dihydro-indol-3-ylidene)-1,3-dihydro-isobenzofuran-1-yl]-acetic acid 2-morpholin-4-yl-ethyl ester as a yellow foam (43 mg, 32%).
