| Originator | Spasmomen,Minapharm Co. | | Definition | ChEBI: Otilonium bromide is a member of benzamides. | | Manufacturing Process | 3 Methods of producing of p-[2-(n-octyloxy)benzoyl]aminobenzoate of Ndiethylammoniumethanol:
1. 21.20 g (0.1 mole) of o-octyloxybenzoyl chloride and aqueous 10% NaOH are added at room temperature, with stirring and by slow dropping to 23.63 g (0.1 mole) of 2-diethylamine-ethyl-p-aminobenzoate in 100 ml of water, in such a manner as to keep the reaction mixture slightly alkaline. After concluding the slow dropping the solution is kept under stirring for 1 h and then the precipitate is collected. This precipitate, p-[2-(n-octyloxy)benzoyl] aminobenzoate of N-diethylammoniumethanol dried and recrystallized from hexane, has a melting point of 81°-82°C.
2. To 31.3 g (0.1 mole) of p-[2-(n-octyloxy)benzoyl]aminobenzoate acid in 300 ml of ethanol, are added 4.0 g (0.1 mole) of finely ground NaOH and the whole is heated to reflux for 1 h. Then 20.25 g (0.15 mol) of 2
Trade diethylaminoethyl chloride are slowly dropped under stirring and the heating is continued for 4 h. After cooling, the sodium chloride formed is filtered off and the solvent is separated by distillation, and the excess of the base, under a reduced pressure. The residue of p-[2-(n-tyloxy)benzoyl]aminobenzoate of Ndiethylammoniumethanol, recrystallized from hexane, has a melting point of 81°-82°C.
3. 11.7 g (0.1 mole) of N-diethylaminoethanol in 200 ml of anhydrous pyridine are added by careful dropping, 34.7 g (0.1 mole) of the chloride of p[2-(n-octyloxy)benzoyl]aminobenzoate acid and the mixture is heated in a water-bath for 3 h. The solvent is then separated by vacuum concentration, the residue is taken up with water, alkalinized and extracted with ether. The collected ether extracts, anhydridised owing to the separation of the solvent, leave a residue of p-[2-(n-tyloxy)benzoyl]aminobenzoate of Ndiethylammoniumethanol which, recrystallized from hexane, has a melting point of 81°-82°C.
p-[2-(n-Octyloxy)benzoyl]aminobenzoate of N-diethylmethylammoniumethyl bromide may be prepared by reaction of the p-[2-(n-octyloxy) benzoylaminobenzoate of N-diethylammoniumethanol with methylating agents such as methylbromide | | Therapeutic Function | Anticholinergic, Spasmolytic |
