実験手順
An aqueous solution of sodium nitrite (337 mg, 4.89 mmol) in water (2 mL) was added dropwise to a suspension of 1H-indazol-4-ylamine D (631 mg, 4.74 mmol) in 6M hydrochloric acid (7.2 mL) at below 0° C. After stirring for 30 minutes, sodium tetrafluoroborate (724 mg) was added to the reaction mixture. A viscous solution resulted, which was filtered and washed briefly with water to yield 1H-indazole-4-diazonium tetrafluoroborate salt E (218 mg, 20%) as a deep red solid.
