The present invention relates to a new process for the preparation of derivatives of 2-phenyl- [1,2,4] triazolo [1,5-a] pyridine of the formula I or a salt thereof wherein R1 means hydrogen , a halogen, an optionally protected hydroxyl group or an optionally protected amino group and is hydrogen or a halogen. The 2-phenyl- [1,2,4) triazolo [1,5-a] pyridine derivatives of the formula I with its 1,2,4-triazole core construct the structural core of a large number of functionalized molecules In medicinal chemistry. |
