实验过程

To 5-amino-2,4-dimethylpyridine (883 mg) were added N,N-diisopropylethylamine (2.1 mL) and N,N-bis(2-chloroethyl)-p-toluenesulfonamide (2.08 g), and the mixture was stirred with heating under reflux. After completion of the reaction, water was added to the reaction mixture, the mixture was extracted with chloroform, and the solvent was evaporated. The obtained residue was purified by column chromatography (chloroform:methanol) to give 1-(4,6-dimethylpyridin-3-yl)-4-(toluene-4-sulfonyl)piperazine (380 mg). The obtained 1-(4,6-dimethylpyridin-3-yl)-4-(toluene-4-sulfonyl)piperazine (380 mg) was dissolved in acetic acid (2 mL), 40% hydrobromic acid (2 mL) was added, and the mixture was stirred at 100° C. After completion of the reaction, the reaction mixture was neutralized with aqueous sodium hydroxide solution, and the mixture was extracted with ethyl acetate. The solvent was evaporated from the organic layer to give the title compound (131 mg).
