Procedure

5-(Indol-3-yl)hydantoin (8.6 g, 0.04 mole) in 200 ml of DMF was added to a solution of sodium (1.84 g, 0.08 mole) in 150 ml of anhydrous C2H5OH. N-(3-Chloropropyl)piperidine hydrochloride (7.9 g, 0.04 mole) was added and the mixture was heated to reflux with stirring for 18 hours, filtered and concentrated in vacuo to dryness. The concentrate was crystallized from aqueous methanol and twice recrystallized from aqueous DMF, yield 1.7 g, mp 233°-4° C.
