By the procedure similar to that described in Example 1, 3-phenyl-5-methylindazole (4.17 g) and dimethylaminopropyl chloride hydrochloride (4.74 g) were treated to obtain an oily product. The product was purified through distillation under reduced pressure to obtain 3.5 g of 1-dimethylaminopropyl-3-phenyl-5-methylindazole (b.p. 185°C/0.5 mmHg).
