Participants

Reaction Steps

A solution of 5-methoxy-4-[3-(morpholin-4-yl) propyloxy]-2-nitrobenzaldehyde (0.26 g, 0.79 mmol) obtained in Step 1 in methanol (8.0 mL) was added with (1H-indazol-3-ylmethyl)triphenylphosphonium bromide (0.73 g, 1.5 mmol) and potassium carbonate (0.34 g, 2.8 mmol), followed by stirring at room temperature for 3.5 hours. The reaction mixture was added with water and the precipitated solid was triturated in methanol to obtain (E)-3-{2-[5-methoxy-4-[3-(morpholin-4-yl)propyloxy]-2-nitrophenyl]vinyl}-1H-indazole (0.39 g, 100%).
