Uses
3-Iodo-1H-indazole is a halogenated indazole compound containing an iodine atom substituent at the 3-position. Due to its highly reactive structure, it can be used in arylation or halogenation reactions. It can also be used in the preparation of fluorinated pyrazoles and indazoles. It can be used in the pharmaceutical field as a raw material or intermediate component in the synthesis of biologically active drugs.
Synthesis
271-44-3
66607-27-0
The synthesis of 3-iodoindazole was carried out according to the method previously reported by Bocchi [28] with slight modifications. The procedure was as follows: 1H-indazole (3 g, 25.4 mmol), iodine (12.7 g, 50.03 mmol) and potassium hydroxide (5.34 g, 95.25 mmol) were dissolved in DMF (7 mL) and the reaction was stirred for 3 h at room temperature. Upon completion of the reaction, saturated sodium bisulfite solution (150 mL) was added to quench the reaction, at which time a precipitate was generated. The precipitate was collected by vacuum filtration and washed with distilled water (3 x 30 mL). The resulting solid was dried overnight in a vacuum oven at 30 °C to give 6.17 g of light yellow solid product in 100% yield. The product was characterized as follows: melting point 136-138 °C (literature value [36]: 134-136 °C); IR (KBr) ν (cm-1): 3086 (NH), 424 (C-I); 1H-NMR δ (ppm): 13.50 (1H, s, H-1), 7.55 (1H, d, J=8.6 Hz, H-7), 7.45- 7.40 (2H, m, H-6 and H-4), 7.19 (1H, dd, J=7.5 Hz, H-5); 13C-NMR δ (ppm): 140.41, 127.22, 126.79, 121.23, 120.39, 110.51, 93.49; HRMS (calculated value C7H5IN2: 243.9497. measured value: 243.9499).
