実験手順

(1H-indazol-3-ylmethyl)trimethylammonium iodide (45.0 g, 142 mmol) obtained in Step 3 was dissolved in DMF (220 mL), and the solution was mixed with triphenylphosphine (44.7 g, 170 mmol), followed by heating under reflux for 2.5 hours. After cooling to room temperature, the reaction mixture was added with diethyl ether and was stirred overnight. The resulting precipitates were collected by filtration to obtain (1H-indazol-3-ylmethyl)triphenylphosphonium iodide (68.3 g, 92%).
