Definitions
- This invention relates to certain novel disubstitutedaminoethoxyphenyl amines, ethers and sulfides and, more particularly, is concerned with novel compounds which may be represented by the following general formula:
- R R R and R are each hydrogen, methyl or ethyl with the proviso that the total number of carbon atoms in the alkylene group is less than 7;
- R is lower alkyl;
- R is lower alkyl; and
- R and R taken together with the N(itrogen) is pyrrolidino, piperidino, morpholino, thiomorpholino or 4-lower alkyl-l-piperazino;
- Z is imino, oxygen or sulphur; and
- R is 4-pyridyl, 3-nitro-2-pyridyl, S-nitro-Z-pyridyl, 5-halo-2-pyrimidyl, 2 benzothiazolyl, 2-ha1o-4-pyrimidyl, 2,6-dibalo-4-pyrimidyl or a p-nitrophenyl group of the following general formula:
- R7 wherein R is hydrogen, nitro or amino.
- Lower alkyl groups contemplated by the present invention are those having from 1 to 4 carbon atoms. Halogen is exemplified by chlorine and bromine.
- the invention includes the novel disubstituted-aminoethoxyphenyl amines, ethers and sulfides and the method of lowering therewith the cholesterol level in blood serum.
- Atherosclerosis is a form of arteriosclerosis where cholesterol and lipoid materials are deposited as plaques in the intima of large and medium sized arteries. Arteriesclerosis is associated with the degeneration of arterial walls by mechanisms not clearly defined. However, there is a statistical correlation between hypercholesteremia and the incidence of cardiovascular disease. For some time it has been considered desirable to lower high cholesterol and lipid levels in man as a possible preventive measure against atherosclerosis.
- hypocholesteremic adjuvants Typical of such substances are lecithin, cottonseed oil, and corn oil.
- Our invention is based upon the discovery that our novel disubstituted-aminoethoxyphenyl amines, ethers and sulfides exert a more powerful hypocholesteremic action than the adjuvants which have been used heretofore. It is not known how the novel compounds of the present invention operate to lower the cholesterol level in blood serum and no theory of why these compounds operate is advanced. It is not intended that the present invention should be limited to any theory as to mechanism.
- novel compounds of the present invention may be readily prepared by the interaction of an 0-, m-, or p-disubstituted aminoethoxy aniline, phenol, or mercaptobenzene with a 2,5-dihalopyrimidine, a 2-halobenzothiazole, a 2,4-dihalo-pyrimidine or a 2,4,6-trihalopyrimidine.

- the intermediate 0- or p-hydroxynitrodiphenyl ether is then treated with an appropriate disubstituted-aminoethyl halide whereupon the desired disubstituted-aminoethoxyphenyl ether is obtained.
- the intermediate 0- or phydroxynitrodiphenyl ether is first converted to its alkali metal alkoxide in an inert solvent such as toluene before treatment with the disubstituted-aminoethyl halide.

- Quaternary ammonium salts may be formed by reaction of the free bases with a variety of organic esters of sulfuric, hydrohalic, and aromatic sulfonic acids.
- the organic reagents employed for quaternary ammonium salt formation are preferably lower alkyl halides.
- other organic reagents are suitable for salt formation, and may be selected from among a diverse class of compounds including benzyl chloride, phenethyl chloride, naphthylmethyl chloride, dimethyl, sulfate, methyl benzenesulfonate, ethyl toluenesulfonate, allyl chloride, methallyl bromide and crotyl bromide.
