The present invention provides a process for preparing pyrrolotriazine compounds of formula (I)
or a pharmaceutically acceptable salt thereof. Also provided are crystalline forms of the pyrrolotriazine compound [4-[[1-(3-fluorophenyl)methyl]-1H-indazol-5-ylamino]-5-methyl-pyrrolo[2, 1-f][1,2,4]triazin-6-yl]-carbamic acid, (3S)-3-morpholinylmethyl ester and pharmaceutical compositions comprising at least one crystalline form, as well of methods of using the crystalline forms in the treatment of a proliferative disease, and methods for obtaining such crystalline forms. The compounds of formula (I), including [4-[[1-(3-fluorophenyl)methyl]-1H-indazol-5-ylamino]-5-methyl-pyrrolo[2,1-f][1,2,4]triazin-6-yl]-carbamic acid, (3S)-3-morpholinylmethyl ester, are useful for inhibiting tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.
本发明提供了制备公式(I)的吡咯三嗪化合物或其药学上可接受的盐的过程。同时,还提供了吡咯三嗪化合物[4-[[1-(3-氟苯基)甲基]-1H-吲唑-5-基]氨基]-5-甲基-吡咯[2,1-f][1,2,4]三嗪-6-基]-碳酸酯,(3S)-3-吗啉甲酯的结晶形式,以及包含至少一种结晶形式的制药组合物,以及使用这些结晶形式治疗增殖性疾病的方法以及获得这些结晶形式的方法。公式(I)的化合物,包括[4-[[1-(3-氟苯基)甲基]-1H-吲唑-5-基]氨基]-5-甲基-吡咯[2,1-f][1,2,4]三嗪-6-基]-碳酸酯,(3S)-3-吗啉甲酯,对于抑制生长因子受体的酪氨酸激酶活性,如HER1,HER2和HER4,因此使它们成为治疗癌症和其他疾病的抗增殖剂,非常有用。
