Related Products of 76006-11-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 76006-11-6, name is 7-Chloro-1H-pyrazolo[3,4-c]pyridine. A new synthetic method of this compound is introduced below.
Trimethylaluminum (23.9 ml_, 47.8 mmol, 2M in toluene) was added to a vigorously stirred solution of 7-chloro-1 H-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. The mixture was cooled to RT and poured into sat. aq. NH4CI. 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, dried (Phase separator) and concentrated under reduced pressure to give 7-methyl-1 H-pyrazolo[3,4- c]pyridine as a solid. MS (LC-MS): 134 [M+H]+; tR (HPLC conditions d): 0.25 min.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,76006-11-6, 7-Chloro-1H-pyrazolo[3,4-c]pyridine, and friends who are interested can also refer to it.
