摘要
以2-溴-3-甲氧基丙酸为原料,采用混合酸酐法合成N-苄基-2-溴-3-甲氧基丙酰胺,对反应中产生的主要杂质进行分离和结构鉴定,并对其产生机理进行了研究。杂质结构经1 H NMR、13 CNMR、IR分析表征确认。
N-Benzyl-2-bromo-3-methoxypropionamide was synthesized from 2-bromo-3-methoxypropionic acid by mixed anhydride methods.The main impurities were separated and analyzed.Furthermore,the mechanism of the production of the main impurities was discussed.The molecular structures of impurities were confirmed by 1H NMR,13C NMR,IR.
