Abstract
1353802 Aryloxypropionamidophenols and intermediates therefor AGFA-GEVAERT AG 5 Aug 1971 [8 Aug 1970] 36938/71 Heading C2C [Also in Division G2] α - (4 - Octadecylphenoxy)propionic acid is prepared by heating 4-octadecylphenol with α- chloro- or α-bromopropionic acid ethyl ester, mixing with sodium methylate solution, refluxing, adding aqueous sodium hydroxide and methyl alcohol and pouring the mixture into water at 0‹ C. and concentrated hydrochloric acid. α-(3-Pentadecylphenoxy)propionic acid and α - (4 cyclohexylphenoxy)propionic acid are prepared similarly. The corresponding acid chlorides are prepared by heating the acid with an excess of thionyl chloride for 3 hours at 70‹ C., and then for 2 hours at 90‹ C. in vacuo. 2-[α-(3- pentadecylphenoxy)propionamido] - 4,6 - dichloro - 5 - methylphenol is prepared by stirring a mixture of acetone, 2-amino-4,6-dichloro-5- methylphenol hydrochloride (prepared as described in German Specification 1,003,586) and N,N-dimethyl-aniline at room temperature and adding α-(3- pentadecylphenoxy)propionic acid chloride. 2 - [α - (4 - octadecyl - phenoxy)- propionamido] - 4,6 - dichloro - 5 - methylphenol and 2 - [α - (4 - cyclohexylphenoxy)- propionamido] - 4,6 - dichloro - 5 - methylphenol are prepared similarly.
