With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.22795-99-9,(S)-(1-Ethylpyrrolidin-2-yl)methanamine,as a common compound, the synthetic route is as follows.
22795-99-9, General procedure: (2-(7-Aza-1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate), (HATU) (1.2 equivalents) was added to a solution of acid (1 equivalent), the appropriate amine (1.5 equivalents) and DIEA (2 equivalents) in dry acetonitrile (10 mL) at room temperature under argon atmosphere. The reaction mixture was stirred at room temperature for 1-2 h. Solvent was evaporated under reduced pressure and the crude product was purified using a Teledyne Isco Combiflash Rf purification machine to provide the desired amide in excellent yield.
22795-99-9 (S)-(1-Ethylpyrrolidin-2-yl)methanamine 643457, achiral-catalyst compound, is more and more widely used in various fields.
