実験手順

Phenyl N-[2,3-dihydro-7-(pyrid-3-yl)benzofuran-5-yl]carbamate (D65) (0.20 g, 0.00060mole) in dry DMF (10 ml) was treated under argon with 5-methoxy-6 trifluoromethyl indoline (D11) (0.13 g, 0.00060 mole) and heated under reflux for 18 hours. The reaction was allowed to cool to ambient temperature and the solvent was removed in vacuo. The residue was dissolved in dichloromethane, washed with deionised water and 10% sodium hydroxide solution, dried (Na2SO4) and evaporated in vacuo. The resulting brown oil was purified by flash column chromatography on silica gel, eluting with 2% methanol/dichloromethane, followed by recrystallisation from ethyl acetate 60-80° petroleum ether to afford the title compound (0.07 g, 26%) as a beige solid.
