실험 절차

The product was prepared in the same manner as described in example 1c using 7-bromo-2-(3-fluorophenyl)-[1,2,4]triazolo[1,5-a]pyridine (1 g, 3.42 mmol) and tert-butyl carbamate (481 mg, 4.11 mmol) as starting materials. The reaction affords 2-(3-fluoro-phenyl)-[[1,2,4]triazolo[1,5-a]pyridin-7-yl]-carbamic acid tert-butyl ester (1.15 g, 102%) as light yellow foam. MS: m/z=329.0 (M+H+).
