3-(1-Pyrrolidinyl)-2-cyclopenten-1-one → HCID 22996624, compound

Participants

Reaction Steps

To 2.245 g (14.85 mmol) of 3-(pyrrolidino)-2-cyclopenten-1-one dissolved in 50 mL of toluene was added 2.5 g (7.61 mmol) of the tetrapyrrolidino titanium. The reaction mixture became red with concomitant appearance of precipitate. The reaction mixture was stirred overnight and then filtered giving a dark red solution. Toluene was removed under reduced pressure to give 2.75 g of red crystalline solid. Yield was 90.6 percent. This product was then recrystallized from 60 mL of hexane to give 1.56 g of the desired product as large red-orange crystals.
