Procedure
The title compound was prepared following procedure described for intermediate A1 step a), but starting from N-(5-bromo[1,2,4]triazolo[1,5-a]pyridin-2-yl)benzamide ((B1), 75 mg; 0.24 mmol; 1.0 eq.) and 2-furanboronic acid (53 mg; 0.47 mmol; 2.0 eq.). Purification by flash chromatography on silica (EtOAc/c-Hex, 45:55) gave the title compound as an off-white powder (19 mg, 26%). HPLC, Rt: 3.24 min. (purity 97.9%). LC/MS, M+(ESI): 305.3, M−(ESI): 303.2.
