反応手順

Under an argon atmosphere 5.0 g (25 mmol) 2-chloro-6-methoxyquinoline in a small amount of THF were added dropwise at −78° C. to 14 mL (28 mmol) of a 2 M lithium diisopropylamide solution (in THF) in 50 mL THF. Then the mixture was stirred for 1.5 h at −78° C. and 4.5 mL (25 mmol) N-benzylpiperidone was added dropwise. The mixture was stirred for a further 15 min with cooling before slowly being heated to RT. The reaction mixture was stirred overnight, evaporated down and purified by flash chromatography on aluminium oxide. The product-containing fractions were combined and evaporated down.
