In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of (E)-2,2,2-trifluoro-N-(2-(2-nitrovinyl)phenyl)acetamides, published in 2014, which mentions a compound: 20028-53-9, Name is 2-Amino-5-chlorobenzaldehyde, Molecular C7H6ClNO, Synthetic Route of C7H6ClNO.
The synthesis of (E)-2,2,2-trifluoro-N-(2-(2-nitrovinyl)phenyl)acetamides and their applications in the preparation of pharmaceutical intermediates were introduced. Using nitrobenzaldehyde as raw material, (E)-2,2,2-trifluoro-N-(2-(2-nitrovinyl)phenyl)acetamides (I) were synthesized via reduction of nitro group, substitution of amino group and addition reaction. The product structures were characterized by 1H NMR and 13C NMR.
The article 《Synthesis of (E)-2,2,2-trifluoro-N-(2-(2-nitrovinyl)phenyl)acetamides》 also mentions many details about this compound(20028-53-9)Synthetic Route of C7H6ClNO, you can pay attention to it, because details determine success or failure
