Potassium Hydroxide → 3-(5-nitro-1H-indol-3-yl)-1-azabicyclo[2.2.2]oct-2-ene

Participants

Reaction Steps

44.8 mmol of 1-azabicyclo[2.2.2]octan-3-one hydrochloride (3-quinuclidinone hydrochloride) and 112 mmol of potassium hydroxide are added to a solution of 22.4 mmol of 5-nitro-1H-indole in 100 ml of water/methanol (1/1), and the mixture is stirred at the boiling point for 48 hours. The crystals which deposit on cooling of the reaction solution are filtered off, washed and dried, giving 3-(5-nitro-1H-indol-3-yl)-1-azabicyclo[2.2.2]-oct-2-ene.
