Reaction Steps

Potassium carbonate (1.37 g, 9.95 mmols) and propargyl bromide (2.4 g, 19.9 mmols) were added to a dimethylformamide (10 ml) solution of N-[2-(5-fluoro-6-hydroxyindan-1-yl)ethyl]propionamide (0.5 g, 1.99 mmols) and stirred at 120° C. for 2 hours. The reaction solution was poured into water, and the organic substance was extracted out with ethyl acetate. The extract was washed with a saturated saline solution and water and then dried with anhydrous magnesium sulfate, and the solvent was removed through distillation under reduced pressure. The resulting residue was purified through silica-gel column chromatography (ethyl acetate) to obtain 0.56 g (yield: 97%) of the target compound.
