| titleOfInvention | Glutamic acid benzyl ester n-carboxylic anhydride |
| abstract | Disclosure of the Invention An object of the present invention is to provide a crystalline polymorph having a high bulk density among the crystalline polymorphs of benzyl ester of glutamic acid N-carboxylic acid anhydride and having excellent storage stability. According to the present invention, the glutamic acid benzyl ester N-carboxylic acid anhydride is dissolved in a solvent of 0.5 L or more per 1 mol of the benzyl glutamic acid N-carboxylic acid anhydride heated at a temperature of not lower than 40 ° C., Benzyl ester of glutamic acid N-hydroxycarboxylic acid having a bulk density of 0.45 g / cm < 3 > or more was obtained by adding crystals at a temperature of not lower than the boiling point of not lower than 40 DEG C by adding at least 1.4 liters of a poor solvent per mol of N- A crystalline polymorph of anhydrous carboxylic acid was obtained. |
