Abstract
The 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. The process allows to obtain the desired products in high yields and purity. The synthesis is starting from the coupling of an acetal with a beta-ketoester; the resultant compound is acetylated and then reacted with a dialkyl acetal of N,N-dimethylformamide to give an intermediate which is cyclized to 5-(2-amino-pyrimidin-4-yl)-2-aryl-1H-pyrrole-3-carboxylic ester; the carboxylic ester is then hydrolyzed and the resultant carboxylic acid is finally condensed with an appropriate form of ammonia to give the desired carboxamide. The compounds prepared according to the process of the invention are endowed with protein kinase inhibiting activity and, more particularly, Cdc7 or Cdc7/Cdks inhibiting activity. The compounds are useful in the treatment of a variety of cancers, cell proliferative disorders and diseases associated with protein kinases.
