Procedure

TBAF (0.4 mmol) 1M solution in THF is added to a solution of cyclopropanecarboxylic acid(5-trimethylsilanylethynyl-[1,2,4]triazolo[1,5-a]pyridin-2-yl)-amide (0.32 mmol) in acetonitrile (4 mL) at room temperature. The reaction mixture is stirred at room temperature until all the starting material disappears by LCMS. The solvent of the reaction is removed under vacuum, and the mixture is redissolved in ethyl acetate. The organic phase is washed with water. The organic layer is dried over MgSO4, filtered and the solvent is removed under vacuum to afford the pure product (70 mg, 97% yield). No further purification is carried out on the product.
