実験手順

A mixture of methyl E-4-[4-(5-chloroimidazo[1,2-α]pyridin-2-ylmethoxy)benzyloxyimino]-4-pbenylbutyrate (550 mg), phenylboronic acid (168 mg), sodium bicarbonate (348 mg), toluene (20 ml), water (2 ml) and methanol (2 ml) was stirred at room temperature for 30 minutes under argon atmosphere. To this was added tetrakis(triphenylphosphine)palladium (0) (80 mg) and heated to reflux for 36 hours. The reaction mixture was cooled to room temperature, the organic layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The residue was subjected to silica gel chromatography to obtain methyl E-4-[4-(5-phenylimidazo[1,2-α]pyridin-2-ylmethoxy)benzyloxyimino]-4-phenylbutyrate (490 mg, yield 82%) as a colorless oil from an ethyl acetate-hexane (3:2, v/v)-eluted fraction.
