The present invention relates to a process for the preparation of a key intermediate (as described herein) used in the synthesis of (+)-trans enantiomer of pyrrolidine substituted flavones, represented by the compounds of formula (1) or pharmaceutically acceptable salts thereof; which are inhibitors of cyclin dependant kinases (CDKs) and can be used in the treatment of proliferative disorders such as cancer. Formula (1) wherein R1 has the meaning as indicated in the claims. The process of the present invention has advantages of higher yield and purity, lower reaction temperature, is consistent and involves the use of non toxic solvents. The process of the present invention allows efficient large-scale synthesis and purity of the product obtained is greater than 97 %.
