| titleOfInvention | Purification method of n-(1(s)-ethoxycarbonyl-3-phenylpropyl)-l-alanine |
| abstract | The present invention provides a purification process in which high quality N- (1 (S) -ethoxycarbonyl-3-phenylpropyl) -L-alanine is obtained in high yield with high productivity suitable for industrial scale applications. It is. N- (1 (S) -ethoxycarbonyl-3-phenylpropyl) -L-alanine contaminated with impurities is crystallized from a mixed solvent of alcohol and water having an alcohol / water volume ratio of 1 to 20 to remove contaminating impurities into the mother liquor. And a crystal of N- (1 (S) -ethoxycarbonyl-3-phenylpropyl) -L-alanine. |
