実験手順

A 1.7 M solution of potassium tert. pentylate in toluene (81 ml, 139 mmol) was added dropwise to a solution of 3-(4-bromo-phenyl)-propionitrile (9.70 g, 46.2 mmol) in 200 ml of THF at rt, followed by addition of ethyl propionate (18.9 ml, 185 mmol). Stirring was continued for 20 min. The reaction mixture was quenched by careful addition of 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water and brine, dried over Na2 SO4 and evaporated. The residue was purified by column chromatography (silica gel, EtOAc/n-hexane 3:7) to yield 1 as a yellow oil.
