Reaction Steps

To a solution of 2-(4-chlorobut-2-yn-1-yl)-1H-isoindole-1,3(2H)-dione (200 mg) in acetonitrile (3 mL) was added diethylamine (188 mg) at room temperature. The reaction mixture was stirred at room temperature for 4 hr, and added to water at room temperature, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtered. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (112 mg).
