An improved, kilogram-scale synthesis of a LTB4 receptor antagonist is reported. The title compound was prepared in four linear steps (seven steps total) and 54% overall yield. The 3,5-bisarylphenol core was obtained in nearly quantitative yield by the condensation of 1-benzotriazol-1-ylpropan-2-one with a chalcone. Although all the intermediates were oils, no chromatography purification was required
报道了一种改进的千克规模的LTB4受体拮抗剂的合成。以四个线性步骤(总共七个步骤)和54%的总产率制备标题化合物。通过将1-苯并三唑-1-基丙烷-2-酮与查耳酮缩合,以几乎定量的产率获得了3,5-双芳基苯酚核。尽管所有中间体均为油,但无需色谱纯化。
