Reaction Steps

(1H-indazol-3-ylmethyl)triphenylphosphonium iodide (3.12 g, 6.00 mmol) was dissolved in methanol (50 mL) and the solution was added with o-nitrobenzaldehyde (1.00 g, 6.60 mmol) and potassium carbonate (2.82 g, 20.40 mmol), followed by stirring at room temperature for 1 hour. The reaction mixture was added with water. The precipitated solid was collected by filtration and then dried. The obtained solid was triturated in methanol to obtain Compound 1 (1.05 g, 76%).
