반응 단계
1.00 g (3.85 mmol) methyl 4-bromo-3-nitro-benzoate are dissolved in 6 ml dioxane with 389 mg (3.85 mmol) morpholin-3-one under a nitrogen atmosphere and 36.6 mg (40 μmol) tris-(dibenzylideneacetone)-dipalladium(0), 67.1 mg (116 μmol) xantphos and 1.75 g (5.38 mmol) caesium carbonate are added. Under a nitrogen atmosphere and with stirring, the reaction mixture is heated to 95° C. for 16 hours. Then it is filtered, the solution is evaporated down i. vac. and evaporated with ether. The residue is further reacted without any more purification. Yield: 1.31 g (quantitative).
