| titleOfInvention | Ortho-alkylated arylamine and preparation method thereof |
| abstract | The invention belongs to the technical field of organic synthesis, and particularly relates to ortho-alkylated arylamine and a preparation method thereof. The structure of the ortho-alkylated arylamine is shown as a formula I, wherein R is 1 One selected from straight chain alkyl, cyclic alkyl, aryl and condensed ring aryl, R 2 One selected from hydrogen, halogen, ester group, carbonyl, nitro, cyano, sulfone group and acyl, R 3 And R 4 Each of which is one of hydrogen, alkyl and aryl substituents. The invention also provides a preparation method of the ortho-alkylated arylamine, which comprises the steps of dissolving the compound shown in the formula II and the compound shown in the formula III in an inert solvent, and reacting under the action of a catalyst to obtain the compound shown in the formula I. The invention provides ortho-alkylated arylamine and a preparation method thereof, which solve the technical problems of low reaction purity of arylamine and unstable intermediate in the prior art. |
