N-甘氨酸的合成方法

Synthesis process of 15 N-glycine

Abstract

本发明提供了一种
The present invention provides synthesis process of 15N-glycine, and prepares 15N-glycine through reaction between 15N-amino methanol and quaternary ammonium salt of haloacetic acid in alcohol solution, 15N-amino methanol is prepared through dissolving formaldehyde in alcohol solution and reacting with 15N-ammonia, and the quaternary ammonium salt of haloacetic acid is prepared through dissolving haloacetic acid in alcohol solution and reacting with tertiary amine. The synthesis process of the present invention can synthesize great amount of 15N-glycine in relatively short time in the same conditions and has 15N-glycine yield higher than 70 %, abundance higher than 99 % and purity higher than 99 %.
