| titleOfInvention | PROCEDURE FOR THE PREPARATION OF TRIMETOXY-BENZA-MIDOHEXANOIC ACID AND ITS SALTS. |
| abstract | Process for the preparation of trimethoxybenzamidohexanoic acid and its salts, of the formula, general ** (see formula) ** Where a means hydrogen or sodium, characterized by reacting an aqueous solution of the sodium salt of 6-aminohexanoic acid with 3,4,5-trimethoxybenzoyl chloride, or another active derivative of the acid (see formula) methoxybenzoic, especially its methyl ester, capable of reacting with an aliphatic amino group, according to the reaction scheme ** (see formula) ** Where m represents chlorine or a group -ogh3, in the presence of an acid acceptor, preferably sodium hydroxide, when m represents chlorine, absorbent of the hydrochloric acid formed in the reaction and, subsequently, acidifying the reaction mass with a mineral acid, hydrochloric preference, precipitating the free acid which, optionally is subjected to further purification treatments and, converting, if desired, to its sodium salt, by neutralization of the acid obtained with a sodium hydroxide solution, followed by precipitation with a water-soluble organic solvent, preferably methanol.
