実験手順

Potassium hydroxide (6.89 g, 0.12 mol) was dissolved in methanol (30 mL). To the solution were added 7-chloroindole (4.65 g, 0.031 mol), 4-piperidone hydrochloride hydrate (9.48 g, 0.061 mol). The mixture was stirred at reflux temperature under nitrogen for about a day, and was cooled and diluted with 50 mL of water, added dropwise. The solid was collected, washed with water and vacuum dried. Yield 5.6 g (78%) as a yellow solid. mp 197°-201° C. FDMS m/e=232 (M+)
