3522-07-4 - Reference Information
| use | 6-methoxy-1H-indazole is a pharmaceutical intermediate. |
| Preparation | 6-methoxy-1H-indazole can be made of 2-fluoro-4-methoxybenzaldehyde and hydrazine prepared by ring-closing reaction. Hydrazine (12.9mL,410.5mmol) was added to a stirred solution of 2-fluoro-4-methoxybenzaldehyde (2.0g,12.97mmol) in THF(20.0mL). The mixture was stirred for 3 days at 95°C to 110°C. Concentrate the mixture to 1/3 of its volume. Add water and precipitate the product. The solids were filtered out, washed with plenty of water and dried in a vacuum oven to obtain the white solid compound 6-methoxy-1H-indazole (1.25g,65%). |
