Participants

Reaction Steps

To a solution of 1.772 g of t-butyl 11-chloro-2-oxo-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate in 10 ml of THF was added 10.1 ml of a 1 M solution of a borane-THF complex in THF under ice-cooling, followed by elevating to room temperature and stirring for 3 hours. To the reaction mixture was added dropwise 10 ml of EtOH, and subsequently 10 ml of a 1 M aqueous sodium hydroxide solution was added dropwise thereto, followed by stirring. The mixed solution was diluted with water, followed by extraction with EtOAc. The organic layer was dried over anhydrous sodium sulfate and then filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (elution solvent: HEX-EtOAc) to obtain 2.007 g of t-butyl 11-chloro-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate as a colorless viscous substance.
