Electric Literature of 76006-11-6 ,Some common heterocyclic compound, 76006-11-6, molecular formula is C6H4ClN3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Trimethylaluminum (23.9 mL, 47.8 mmol, 2M sol. in toluene) was added to a vigorously stirred solution of 7-chloro-iH-pyrazolo[3,4-c]pyridine (3.67 g, 23.9 mmol) and Pd(PPh3)4 (1.38 g, 1.19 mmol) in THF (109 mL) under argon. The reaction mixture was stirred at 65C for 16 h, cooled to RT and poured into sat. aq. NH4CI solution. The resulting suspension was filtered, the solid washed with water and discarded. The filtrate and the combined washings were extracted with EtOAc (3x). The combined organic extracts were washed with brine then dried (phase separator) and concentrated to give 7-methyl-i H-pyrazolo[3,4-c]pyridine as a solid. MS (LC/MS): 134 [M+H]+, tR (HPLC conditions d): 0.25 mm.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 76006-11-6, 7-Chloro-1H-pyrazolo[3,4-c]pyridine, other downstream synthetic routes, hurry up and to see.
