PROCESS FOR THE PREPARATION OF 2-PHENYL-[1,2,4]TRIAZOLO[1,5-A]PYRIDINE DERIVATIVES

-

Paragraph 0097; 0098; 0099; 0100, (2014/12/09)

The invention relates to a novel process for the preparation of 2-phenyl-[1,2,4]triazolo[1,5-a]pyridine derivatives of formula I or of a salt thereof wherein R1 stands for hydrogen, a halogen, for an optionally protected hydroxyl group or for an optionally protected amino group and R2 is hydrogen or a halogen. 2-Phenyl-[1,2,4]triazolo[1,5-a]pyridine derivatives of formula I with their 1,2,4-triazole nucleus build the structural core of a great number of functionalized molecules in medicinal chemistry.
