실험 절차

To a solution of 0.868 gm (15.5 mMol) potassium hydroxide in 8 mL methanol were added 1.0 gm (4.42 mMol) 5-(2-furoyl)amino-1H-indole and 0.774 mL 1-ethyl-4-piperidone and the solution was stirred at reflux for 18 hours. The reaction mixture was cooled to ambient and then diluted with ice/water. The resultant precipitate was collected and dried under vacuum. This solid was purified by radial chromatography (2 mm silica), eluting with a gradient of dichloromethane containing 5-7.5% methanol and 0.5-1.0% ammonium hydroxide. The product was then crystallized from ethyl acetate to give 0.715 gm (48.3%) of the title compound as a bright yellow powder.
