Preparation method of N-methyl-4-bromoaniline

The invention provides a preparation method of N-methyl-4-bromoaniline, belonging to the technical field of organic synthesis. The preparation method solves the technical problems that existing monomethylation reaction steps of aniline are tedious and the purity of prepared products is low. The method comprises the following steps: 1, adding dichloroethane and N-methylaniline into a first reactor,then dropwise adding acetic anhydride into the first reactor, and carrying out stirring; 2, dropwise adding a brominating agent into the formed reaction system, carrying out stirring, carrying out sampling analysis until the content of N-methyl acetanilide is less than 1%, adding sodium sulfite, carrying out stirring, and carrying out suction filtration; 3, adding the solid N-methyl-4-bromoacetanilide obtained through suction filtration in the step 2 into a second reactor, then adding hydrochloric acid with a mass concentration of 15%, carrying out heating reflux for 3 h, and carrying out sampling analysis until a reaction is completed; and 4, cooling, neutralizing and extracting the reaction system in the step 3, and recovering the solvent to obtain the colorless transparent liquid N-methyl-4-bromoaniline. The N-methyl-4-bromoaniline prepared by using the method is high in purity, and has a content of greater than 98%.

Practical and metal-free electrophilic aromatic halogenation by interhalogen compounds generated in situ from N-halosuccinimide and catalytic TMSCL

Halomonochloride compounds (ClCl, BrCl, ICl) generated in situ from N-halosuccinimide and catalytic chlorotrimethylsilane (TMSCl, 0.1 equiv) can efficiently halogenate aromatic compounds to give halogenated products in good to excellent yields and selectivities. The reaction can be carried out at room temperature or at lower temperatures, requires only one hour, is practical to apply to a wide range of substrates, and provides a simple access to a variety of haloarene compounds.

Functionalized analogues of Tr?ger's base: scope and limitations of a general synthetic procedure and facile, predictable method for the separation of enantiomers

A major stumbling block in the applications of enantiomerically pure Tr?ger's base analogues is their poor availability. We have therefore developed a facile method for the enantioseparation of functionalized Tr?ger's base analogues possessing various sub
