Procedure

N-(2-Fluoro-4-chloro-5-cyclopentyloxyphenyl)-3,4,5,6-tetrahydrophthalimide (1.00 g, 2.75 mmol), propargylamine (0.180 g, 3.27 mmol), and benzene (25 ml) as a solvent were placed into a round bottom flask (50 cc) and stirred overnight at room temperature. After completion of the reaction, the solvent was distilled off under reduced pressure, and the resulting crude product was recrystallized from chloroform/hexane to obtain N-(2-fluoro-4-chloro-5-cyclopentyloxyphenyl)-N'-propargyl-3,4,5,6-tetrahydrophthalamide as white crystals (0.366 g, 31.8% yield).
