Reaction Steps
A mixture of 1,2,3,4-tetrahydroquinoline (4.0 mL, 32 mmol), 2-chlorocyclohexanone (3.6 mL, 32 mmol) and pyridine (3.0 mL, 38 mmol) in 2-methoxyethanol (80 mL) was heated to 120° C. for 48 h and was then concentrated. The black gummy residue was extracted into ethyl acetate and washed with 2 N HCl. The organic layer was dried (MgSO4) and concentrated. The material was purified by flash column chromatography (elution with 5% ethyl acetate-hexanes) to provide a clear oil which was dissolved in hexane. Upon cooling the solution to −78° C. a precipitate formed. The precipitate was collected to provide 5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazole. MS (ES) m/z 212.1.
