Reaction Steps

To a solution of 5-hydroxy-3-(quinol-4-ylmethylene)-2-oxindole (2.883 g, 10 mmol) in toluene (100 ml) was added portionwise under nitrogen NaH 80% (0.300 g, 10 mmol). After salification was complete, 3-chloro-1,2-propanediol (1.547 g, 14 mmol) was added and the mixture heated to reflux for 5 h. After cooling, water was added, the organic phase washed and evaporated to dryness. The residue was submitted to flash chromatography, using CHCl3 --MeOH mixtures as eluant to give pure title compound in about 70% yield.
