The present invention relates to a method for synthesizing diversely substituted purines starting from a pyrimidine. Formula (I). The method comprises the formation of an amidine group on the pyrimidine by implementing a Vilsmeier type reagent, the functionalization of the pyrimidine with an amine and the cyclization to form the purine nucleus. Optional steps can also be performed in order to further functionalize the molecule. The invention also relates to new purines and new intermediate product.

The instant invention provides compounds of formula I which are PI3K-delta inhibitors, and as such are useful for the treatment of PI3K-delta-mediated diseases such as inflamation, asthma, COPD and cancer.
Highly substituted purines were synthesized in good to high yields through a one-pot straightforward metal-free scalable method, using the Traube synthesis adapted to Vilsmeier-type reagents. From 5-amino-4-chloropyrimidines, new 9-aryl-substituted chloropurines and intermediates for peptide nucleic acid synthesis were prepared. Variant procedures allowing a rapid synthesis of ribonucleosides and 7-benzylpurine
