実験手順

A 1 ml portion of anisole and 0.7 ml of trifluoroacetic acid were added to 7 ml of dichloromethane solution containing 200 mg (0.70 mmol) portion of 2-t-butoxycarbonyl-9-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole and stirred at room temperature for 4 hours. The solvent was removed by evaporation under a reduced pressure and the residue was recrystallized from acetone-diisopropyl ether to obtain 9-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole quantitatively as trifluoroacetate.
