Potassium Hydroxide → HCID 18797384, compound

Participants

Reaction Steps

To a solution of 5.02 gm (89.0 mMol) potassium hydroxide in 50 mL methanol were added 5.00 gm (35.17 mMol) 5-cyano-1H-indole and 7.8 mL (42.08 mMol) 1-benzyl-4-piperidone. The reaction mixture was stirred for 16 hours at reflux and then was allowed to cool. The reaction mixture was then concentrated under reduced pressure. The resultant residue was subjected to flash chromatography, eluting with dichloromethane containing 5% methanol. Fractions shown to contain product were combined and concentrated under reduced pressure to give 11.0 gm of the title compound of sufficient purity to be used in subsequent reactions.
