New Advances in Chemical Research, May 2021. Application In Synthesis of 4-(4-((2,4-Dioxothiazolidin-5-ylidene)methyl)-2-methoxyphenoxy)-3-(trifluoromethyl)benzonitrile, Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. In a document type is Article, and a compound is mentioned, 1055361-35-7, 4-(4-((2,4-Dioxothiazolidin-5-ylidene)methyl)-2-methoxyphenoxy)-3-(trifluoromethyl)benzonitrile, introducing its new discovery.
The synthesis of various substituted 4-methoxy-1H-quinolin-2-thiones from various substituted aniline with malonic acid, phosphorousoxychloride, sodium methoxide glacial acetic acid and thiourea under different conditions is described. All these substituted 4-methoxy-1H-quinolin-2-thiones were synthesized from four steps; the first step involved the synthesis of substituted 2,4-dichloro quinoline from aniline (substituted), with malonic acid and phosphorous-oxychloride. In the second step, the substituted 2,4-dichloro compound was heated with freshly prepared methanolic sodium methoxide solution to give 2,4-dimethoxy quinoline compounds, it was then refluxed with glacial acetic acid and hydrochloric acid to get the substituted 4-methoxy-1H-quinolin- 2-one. The final steps involves with an objective of introducing a chloro in the position 2 of the quinolone system, the substituted 4-methoxy-1H-quinolin-2-one was refluxed with distilled PoCl3 chloroform. The substituted 2-chloro-4-methoxy quinoline was then refluxed with thiourea and alcohol to get substituted 4-methoxy-1H-quinolin-2-thiones. The purity of the synthesized compound was judged by their C, H and N analysis and the structure was analyzed on the basics of mass, FT-IR and 1H NMR.
In the meantime we’ve collected together some recent articles in this area about 1055361-35-7 to whet your appetite. Happy reading!
