Participants

Reaction Steps

To a solution of 201 mg of t-butyl 11-methyl-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate in 2 ml of pyridine was added 0.1 ml of ethyl chloroformate, followed by stirring at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (elution solvent: HEX-EtOAc) to obtain 261 mg of 8-t-butyl 1-ethyl 11-methyl-3,4,6,7,9,10-hexahydro-1H-azepino[4,5-g]quinoline-1,8(2H)-dicarboxylate as a colorless viscous substance.
