Reaction Steps

N-(4-Bromopyrazolo[1,5-a]pyridin-2-yl)cyclopropanecarboxamide (4.66 g, 17 mmol), 4-formylphenyl boronic acid (3.06 g, 20.4 mmol), PdCl2dppf (0.37 g, 0.45 mmol) and Na2CO3 (3.6 g, 34 mmol) were stirred in 1,4-dioxane (140 mL) and water (28 mL) at 100° C. for 3 h. The reaction mixture was cooled to room temperature, filtered through celite, washed through with DCM and concentrated in vacuo. The residue was triturated with EtOAc and dried in vacuo to afford N-(4-(4-formylphenyl)pyrazolo[1,5-a]pyridin-2-yl)cyclopropanecarboxamide.
