HCID 67774935[2-(2-Fluoro-pyridin-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-carbamic acid tert-butyl esterYield 83.5%

Procedure

The product was prepared in the same manner as described in example 1c using 7-bromo-2-(2-fluoropyridin-4-yl)-[1,2,4]triazolo[1,5-a]pyridine (1.2 g, 4.09 mmol) and tert-butyl carbamate (576 mg, 4.91 mmol) as starting materials. The reaction affords [2-(2-fluoro-pyridin-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-carbamic acid tert-butyl ester (1.126 mg, 83.5%) as light brown powder. MS: m/z=330.0 (M+H+).
