Sodium Carbonate → 2-(Furan-2-yl)aniline

참여 물질

반응 단계

To a solution of 2-bromoaniline (137 mg, 0.80 mmol) in THF (4.0 ml) was added 2-furanboronic acid (89 mg, 0.80 mmol), tetrakis-(triphenylphosphine)palladium (0) (92 mg, 0.08 mmol) and sodium carbonate solution (2M, 2.0 ml, 4.0 mmol). The mixture was heated in a sealed tube using a microwave reactor (20 W) at 130° C. for 25 min. This procedure was carried out 5 times and the reaction mixtures were combined. The mixture was separated and the aqueous layer extracted with EtOAc. The combined organic layers were dried and evaporated in vacuo. The residue was purified by flash chromatography on silica (eluant pet. ether:EtOAc 85:15) to give a brown oil; yield 211 mg, 33%.
