With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.57319-65-0,6-Aminoisobenzofuran-1(3H)-one,as a common compound, the synthetic route is as follows.,57319-65-0
Example 68; 2-(3-Oxo-l,3-dihydro-isobenzofuran-5-yIcarbamoyl)-pyrrolidine-l-carboxylic acid benzyl ester (Compound 6068)Using General Procedure C from 0.075 g (0.5 mmol) of 6-Amino-3H- isobenzofuran- 1 -one. MS : 381.1 (M+H4). General Procedure C; A mixture of (S)-Pyrrolidine-l,2-dicarboxylic acid 1-benzyl ester (F.W. = 249.27, 0.15 g, 0.6 mmol), HATU (F.W. = 380.25, 0.209 g, 0.55 mmol), and DIEA (0.1 mL, 0.76 mmol) in DMF (5 mL) was stirred at room temperature for 1 h.. This mixture had to be prepared each time for the reactions of the amines described in the following Examples. The individual mixtures were stirred at room temperature for 20 h., then filtered and separated by reverse phase HPLC (20-100% of buffer B; buffer A: water containing 0.1% TFA; buffer B: MeCN containing 0.1%TFA). The combined fraction was evaporated to dryness to furnish the desired products.
The synthetic route of 57319-65-0 has been constantly updated, and we look forward to future research findings.
