Reaction Steps

2-dimethylamino-5-[1-(4-hydroxyindol-3-yl)ethyl]2-oxazolin-4-one (120 mg) was dissolved into dimethylformamide (3 ml). Potassium carbonate (115 mg) and indomethane (156 l) were added. The mixture was stirred for 3 hours at room temperature and additional indomethane (78 μl) was added. The mixture was stirred for 36 hours at room temperature. To the reaction mixture was added water and the whole was extracted with ethyl acetate. The extract was washed with brine and dried over magnesium sulfate. Concentration of the ethyl acetate solution gave a residue, which was subjected to silica gel chromatography. Elution with hexane-acetone (1:1) provided 2-dimethylamino-5-[1-(4-methoxyindol-3-yl)ethyl]-2-oxazolin-4-one (54 mg).
