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. 6228-73-5, name is Cyclopropanecarboxamide, A new synthetic method of this compound is introduced below., HPLC of Formula: C4H7NO
General procedure: Synthesis of 2-methyl-5-((9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-yl)amino)isoindolin-1-one (4) Procedure A: A mixture of 9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-amine (3, 0.10 g, 0.37 mmol), 5-bromo-2-methylisoindolin-1-one (2, 0.10 g, 0.45 mmol), sodium tert-butoxide (54 mg, 0.56 mmol) and XPhos (5 mg, 0.01 mmol) in toluene (10 mL) was degassed with argon for 30 min. Tris(dibenzylideneacetone)dipalladium(0) (20 mg, 0.022 mmol) was added under argon atmosphere and the reaction mixture was heated at 100 C. for 12 h. After completion of the reaction, the reaction mixture was filtered through celite pad and the filtrate was concentrated. The crude residue was purified by silica gel column chromatography using 0-10% ethyl acetate in hexanes as eluent to afford 2-methyl-5-((9-((2-(trimethylsilyl)ethoxy)methyl)-9H-purin-6-yl)amino)isoindolin-1-one (4). Yield: 0.11 g, 71%; MS (ESI) m/z 411 [M+1]+.
The synthetic route of 6228-73-5 has been constantly updated, and we look forward to future research findings.
