Electric Literature of 862730-04-9, 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. 862730-04-9, name is 3-Iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine. A new synthetic method of this compound is introduced below.
Synthesis of 3-(4-amino-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-N-(4,5-dihydrothiazol-2-yl)benzamide (BA30); A solution of [3-((4,5-dihydrothiazol-2-yl)carbamoyl)phenyl]boronic acid (19 mg, 0.08 mmol) in EtOH (3.3 ml) was added to a solution of 3-iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (20 mg, 0.07 mmol) in DME (12 ml). Pd(PPh3)4 (16 mg, 0.014 mmol) and saturated Na2CO3 (1.9 ml) were added and the reaction was heated to 80 C. under an argon atmosphere overnight. After cooling, the reaction was extracted with saturated NaCl and CH2Cl2. Organic phases were combined, concentrated in vacuo and purified by RP-HPLC (MeCN:H2O:0.1% TFA) to yield BA30 (17.8 mg, 67% yield).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,862730-04-9, 3-Iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine, and friends who are interested can also refer to it.
