The process for the synthesis of the above defined and enumerated products comprises the preparation by condensation of the chloride of o-hydroxy-benzoic acid and the suitable chlorides of substituted o-hydroxy-benzoic acids, with amino-benzoic acids, with the Diethyl-amino-ethyl p-amino-benzoate and with amino-acetic acid, in dioxane, in the presence of pyridine.



   By way of example, the process for preparing p- (o'ethoxybenzoyl-amino) - benzoic acid is given below.



   72 g of o-ethoxybenzoic acid chloride are poured into a solution of 55 g. p-amino-benzoic acid in 300 ml. of anhydrous dioxane and 31 ml of anhydrous pyridine.

 <Desc / Clms Page number 4>

 



   The mixture is warmed in a water bath for 2 hours. After cooling, the precipitate which separates is filtered and dissolved in 5% sodium bicarbonate. The solution obtained is aoidified with concentrated HCl and the precipitate obtained is filtered, which, crystallized from ethanol, has a melting point of 237-238 C.



   It appears that the products mentioned have a pharmacological activity as antirheumatic analgesics hitherto unknown; some products of this type have only been tried sometimes as choleretics. P- (Hydroxy-benzoyl. Amino) -benzoic acid has been used industrially because of the affinity it has, in the sodium salt form, for plant fiber.
