PROCEDURE FOR THE PREPARATION OF THE 4-AMINOHEX-5- ANOIC ACID OR A SALT OF THE SAME. |
| abstract |
Process for the preparation of 4-aminohex-5-enoic acid or a salt thereof, characterized in that it consists in treating a pyrrolidone compound of the formula **(Formula)** where R1 is hydroxy, amino, or tertiary butoxy with an excess of a strong acid, optionally preceded by treatment with an excess of a strong base at a temperature of from about 100° to 150°C, for about 2 to 24 hours followed by treatment with a base or application to an acid ion exchange resin when the free base is desired. |
