Reaction Steps

A stirred solution of 4-fluoroindole (400 mg, 3.0 mmol), t-butyl-4-oxo-1-piperidinecarboxylate (650 mg, 3.3 mmol), and pyrrolidine (0.62 mL, 7.4 mmol) in ethanol (10 mL) was heated at reflux for 16 hours. Solvent was evaporated and the residue subjected to chromatography on silica gel with 20% ethyl acetate/hexanes to afford a yellow solid (250 mg, 27%).
