Adding a certain compound to certain chemical reactions, such as: 330794-31-5, 1-Cyclopentyl-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Safety of 1-Cyclopentyl-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine, blongs to pyrimidines compound. Safety of 1-Cyclopentyl-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine
Synthesis of tert-butyl 5-(4-amino-1-cyclopentyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-1H-indole-1-carboxylate (BA88); A solution of tert-butyl 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-1-carboxylate (130 mg, 0.38 mmol) in EtOH (3.3 ml) was added to a solution of 3-iodo-1-isopropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (50 mg, 0.15 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 RP-HPLC (MeCN:H2O) to yield BA88. ESI-MS (M+H)+ m/z calcd 419.2, found 419.1.
