Abstract

1351395 Alkoxy - benzoyl - acetanilides and intermediates therefor AGFA-GEVAERT AG 24 March 1972 [25 March 1971] 13837/72 Heading C2C [Also in Division G2] 2 - Tetradecyloxybenzoyl - 4<SP>1</SP>- methylacetanilide is prepared by boiling 4-aminotoluene and methyl 2 - tetradecyloxybenzoylacetate in xylene. Methyl 2-tetradecyloxybenzoylacetate is prepared by boiling α-(2-tetradecyloxybenzoyl) acetoactic acid ethyl ester, 30% by weight sodium methoxide solution and methanol, pouring into water, acidifying and extracting with ether. α - (2 - Tetradecyloxybenzoyl)acetoacetic acid ethyl ester is prepared by boiling 2-tetradecyloxybenzoyl chloride and sodium acetoacetic acid ethyl ester in benzene, pouring into ice water, and acidifying with 10% by weight hydrochloric acid. 2-Tetradecyloxybenzoyl chloride is prepared by adding thionyl chloride to fused 2 - tetradecyloxybenzoic acid. 2 - Tetradecyloxybenzoic acid is prepared by refluxing methyl 2 - tetradecyloxybenzoate dissolved in ethanol with aqueous potassium hydroxide, stirring into water and acidifying with 10% by weight hydrochloric acid. Methyl 2-tetradecyloxybenzoate is prepared by boiling sodium metal dissolved in ethylene glycol monomethyl ether followed by the addition of methyl salicylate in ethylene glycol monomethyl ether, adding tetradecylbromide dropwise, boiling, cooling and stirring into water. 2 - Tetradecyloxybenzoyl - 2<SP>1</SP>- methoxyacetanilide 2 - tetradecyloxybenzoyl - 2<SP>1</SP> - chloro- 5<SP>1</SP> - N - methylsulphamyl - acetanilide and 2- tetradecyloxybenzoyl - 4<SP>1</SP>- methyl - sulphonyl acetanilide are prepared in a similar manner to 2- tetradecyloxybenzoyl - 4<SP>1</SP>- methylacetanilide. 2 - Tetradecyloxybenzoyl - 4<SP>1</SP>- methyl - chloroacetanilide is prepared by adding dropwise sulphuryl chloride in chloroform while cooling with ice water to 2-tetradecyloxybenzoyl-4<SP>1</SP>- methylacetanilide in chloroform. 2 - Tetradecyloxybenzoyl - 2<SP>1</SP> - methoxy - chloroacetanilide, 2 - tetradecyloxybenzoyl - 2<SP>1</SP> - chloro - 5<SP>1</SP> - N- methylsulphamyl - chloroacetanilide and 2 - tetradecyloxybenzoyl - 4<SP>1</SP>- methylsulphonyl - chloroacetanilide are prepared similarly.
