The present invention relates to a process for the preparation of 5-(2-amino- pyrimidin-4-yl)-2-aryl-lH-pyrrole-3-carboxamides and to the useful intermediate compounds of such process. 5-(2-Amino-pyrimidin-4-yl)-2-aryl-lH-pyrrole-3-carboxamides are described and claimed in WO2007110344, which also discloses processes for their preparation. These compounds can be advantageously prepared through a process which allows to obtain the desired products in high yields and purity and with a limited number of steps. The synthesis is starting from a cyano pyrrole derivative, and is characterized from the final hydrolysis of 5-(2-amino-pyrimidin-4-yl)-2-aryl-lH-pyrrole-3- carbonitrile. The compounds prepared according to the process of the present invention are endowed with protein kinase inhibiting activity and, more particularly, Cdc7 or Cdc7/Cdks inhibiting activity. The compounds are therefore useful in the treatment of a variety of cancers, cell proliferative disorders and diseases associated with protein kinases.
本发明涉及一种制备5-(2-氨基嘧啶-4-基)-2-芳基-1H-吡咯-3-羧酰胺的方法,以及该过程中有用的中间化合物。在WO2007110344中描述并声明了5-(2-氨基嘧啶-4-基)-2-芳基-1H-吡咯-3-羧酰胺,并且还揭示了它们的制备方法。这些化合物可以通过一种允许以高收率和纯度,并且步骤有限的方法制备得到。该合成是从一个氰基吡咯衍生物开始的,并且其特点在于最终水解5-(2-氨基嘧啶-4-基)-2-芳基-1H-吡咯-3-羰基腈。根据本发明的方法制备的化合物具有蛋白激酶抑制活性,更具体地说,是Cdc7或Cdc7/Cdks抑制活性。因此,这些化合物在治疗各种癌症、细胞增殖性疾病和与蛋白激酶相关的疾病方面是有用的。
