Reaction Conditions

Reaction Steps

To a solution of 460 mg of t-butyl 11-bromo-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate in 9 ml of dioxane were added 1.6 ml of a 2 M aqueous potassium carbonate solution under an argon atmosphere, and subsequently 449 mg of trimethylboroxine and 70 mg of tetrakistriphenylphosphine palladium, followed by stirring at 90° C. for 13 hours. The reaction mixture was allowed to cool, filtered, and then concentrated under reduced pressure, the resulting residue was diluted with EtOAc, and the organic layer was washed with water and saturated brine. The solvent was evaporated under reduced pressure and the resulting residue was purified by silica gel chromatography (elution solvent: HEX-EtOAc) to obtain 380 mg of t-butyl 11-methyl-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate.
