Procedure

In 200 ml of tetrahydrofuran in a 500 ml round bottom flask under a nitrogen atmosphere was added (+-)-α-(bromoacetyl)tryptophan (3.25 mg, 0.01 mol), followed by 4-phenylpiperazine (3.24 mg, 3.1 ml, 0.02 mol), added portionwise over five minutes. Three minutes after addition of the 4-phenylpiperazine, a precipitate formed. The reaction mixture was stirred at room temperature for about 18 hours.
