Reaction Steps

To a solution of [2-(3-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-carbamic acid tert-butyl ester (5.5 g, 16.2 mmol) in DCM (100 ml) was added a solution of HCl in dioxane (4 N, 20 ml). The resultant reaction mixture was stirred at 25° C. for 16 h. Volatiles were removed in vacuum, and the resultant residue was dried under vacuum to give 2-(3-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylamine (5 g, quant) as light yellow solid. LC-MS: m/z=241.0 [M+H]+.
