Participants

Reaction Steps

The mixture of benzhydryl-piperidin-4-yl-amine hydrogen bromide salt (1.74 g, 5 mmol, 1.0 eq.), N-(2-bromoethyl)phthalimide (1.27 g, 5 mmol, 1.0 eq.), K2CO3 (1.73 g, 12.5 mmol, 2.5 eq.), and NaI (1.05 g, 7.0 mmol, 1.4 eq.) in 2-butanone (20 ml) was refluxed for 2-3 hours. The mixture was then cooled to room temperature. The white solid was filtered off and was washed with small amount of CHCl3. The filtrates were combined and concentrated. The resulted residue was dissolved in CHCl3 (100 ml). The solution was washed with water (3×20 ml), then dried over anhydrous Na2SO4. After removed all solvent, the crude product 2-{2-[4-(benzhydryl-amino)-piperidin-1-yl]-ethyl} -isoindole-1,3-dione was yielded (2.70 g).
