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., category: pyrimidines
Synthesis of 1-isopropyl-3-(2,3-dimethoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (BA65); A solution 2,3-dimethoxyphenylboronic acid (105 mg, 0.58 mmol) in EtOH (3.3 ml) was added to a solution of 3-iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (70 mg, 0.23 mmol) in DME (12 ml). Pd(PPh3)4 (30 mg, 0.03 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 silica gel column chromatography [MeOH-CH2Cl2, 2:98] to yield BA65 (63 mg, 88% yield). ESI-MS (M+H)+ m/z calcd 314.1, found 314.1.
