Abstract
The present invention relates to a process for the preparation of 5-(2-amino-pyrimidin-4-yl)-2-aryl-1H-pyrrole-3-carboxamides and to the useful intermediate compounds of such process. 5-(2-Amino-pyrimidin-4-yl)-2-aryl-1H-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-1H-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.
