Reaction Steps

To a solution of 2-iodophenyl hydrazine hydrochloride (1.0 eq.) and 4-piperidone (1.0 eq.) in 2,2,2-trifluoroethanol was added 12 N HCl (2.0 eq.). The reaction mixture was heated at 60–65° C. for 3 h and cooled to rt. then filtered. The residue was purified by column chromatography to provide 6-iodo-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole in 69% yield.
