反応手順

To a solution of 3-bromo-4-(2-thiophen-3-yl-ethoxy)-benzonitrile (4.50 g) in DMF (20 mL) was added palladium acetate (327 mg), triphenylphosphine (766 mg) and potassium carbonate (4.03 g) and the reaction heated at 90° C. for 16 h. After cooling to room temperature the mixture was diluted with ethyl acetate (60 ml) and filtered. The filtrate was washed with brine (80 mL), dried (MgSO4), reduced in vacuo and purified on silica to give 4,5-dihydro-6-oxa-1-thia-benzo[e]azulene-9-carbonitrile.
