Bis (trimethylsilyl) amides are converted into nitriles with high yields when they are treated wich a catalyst (tetrabutylammonium fluoride, Lewis acids or iron phthalocyanine).
双(三甲基甲硅烷基)酰胺经过催化剂(氟化四丁基铵,路易斯酸或酞菁铁)处理后,可以高产率转化为腈。

The present invention relates to processes for the preparation of deferasirox, an oral iron chelator developed to treat iron overload due to e.g. multiple blood transfusions. The present invention further provides novel deferasirox pseudopolymorphs and a novel amorphous form of deferasirox, processes for their preparation, as well as pharmaceutical compositions comprising same, and use thereof in treating iron overload.
