実験手順

A mixture of 90 mg (0.58 mmol) of 2-(hydroxymethyl)phenylboronic acid, 120 mg (0.39 mmol) of (3R)-N-(4-bromophenyl)-1-azabicyclo[2.2.2]octane-3-carboxamide, 1.16 ml (1.16 mmol) of 1N sodium hydroxide solution, 30 mg (0.04 mmol) of 1,1′-bis(diphenylphosphino)ferrocenepalladium(II) chloride and 1 ml of DMF is heated at 80–85° C. for 42 h. The solvent is removed under reduced pressure. The crude product is purified by chromatography on silica gel 60 (mobile phase: dichloromethane→dichloromethane/methanol/ammonia 80:20:2). 56 mg (39% of theory) of the title compound are obtained.
