Adding a certain compound to certain chemical reactions, such as: 37045-73-1, name is 3-(Methylsulfonamido)aniline, belongs to amides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 37045-73-1, Computed Properties of C7H10N2O2S
General procedure: To a solution of N-[4-[5-(3-aminophenyl)-1,2,4-oxadiazol-3-yl]-3-chlorophenyl]-3-pyridinecarboxamide (VIc)(0.2 g, 0.51 mmol, 1 equiv) in THF (20 ml) was added phosgene(15wt % in toluene, 1.7 ml, 2.55 mmol, 5.0 equiv) and the reactionmixture was refluxed under N2 for 4 h. Upon the reactioncompletion as indicated by TLC the solution was concentratedunder reduced pressure, flushed with dry toluene. To theresulting residuewas added THF (20 ml), the appropriate aniline(0.77 mmol, 1.5 equiv) and DIPEA (0.132 g, 178 ml, 1.02 mmol, 2equiv) and the reaction mixture was refluxed under N2 overnight.Upon completion of the reaction as indicated by TLC, thesolution was concentrated, and the residue was purified bychromatography to give the desired final products (25-50).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-(Methylsulfonamido)aniline, and friends who are interested can also refer to it.
