| titleOfInvention | Glutamic acid benzyl ester N-carboxylic anhydride |
| abstract | It is an object of the present invention to provide a crystalline polymorph having a high bulk density of the crystalline polymorphs of glutamic acid benzyl ester N-carboxylic anhydride and having excellent storage stability. To do. According to the present invention, glutamic acid benzyl ester N-carboxylic anhydride is dissolved in 0.5 L or more of solvent per mole of glutamic acid benzyl ester N-carboxylic anhydride heated to a temperature of 40 ° C. or more and less than boiling point, The bulk density is 0.45 g / cm 3 by adding 1.4 L or more poor solvent per mole of glutamic acid benzyl ester N-carboxylic anhydride at a temperature, precipitating crystals at a temperature of 40 ° C. or higher and lower than the boiling point, and cooling. The above crystalline polymorph of glutamic acid benzyl ester N-carboxylic anhydride could be obtained. |
