Reaction Conditions

Reaction Steps

(4-tert-Butylphenyl)hydrazine hydrochloride (1 equiv.) is taken in 7% sulfuric acid in 1,4-dioxane. 1-Methylpiperidin-4-one hydrochloride (0.76-1.4 equiv.) is added and the contents are stirred at 80° C. for 3 h. The reaction is monitored by TLC and LCMS. After completion of the reaction, the reaction mixture is concentrated and then quenched with aq. NaHCO3 solution, followed by extracted with EtOAc. The organic layer is dried over anhydrous sodium sulfate, evaporated to dryness and purified by column chromatography (5% MeOH-DCM) to afford 8-tert-butyl-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole.
