With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.216144-45-5,4-(4-Methylpiperazin-1-yl)benzylamine,as a common compound, the synthetic route is as follows.
Examples 52 to 79a) The derivatives of Examples 52 to 79 were prepared in parallel synthesis in the following manner:A solution of 100 mg of 2-[(phenoxycarbonyl)amino]-1,3-benzothiazol-6-yl 2,6-dichlorobenzenesulfonate in 1 cm3 of tetrahydrofuran is placed in each tube of a Stem, with stirring. To each tube is added 1 equivalent of amine and 0.279 cm3 of triethylamine in cases 66 and 79; the mixture is then stirred for about 18 hours at a temperature in the region of 20 C. 5 cm3 of dichloromethane and 3 cm3 of aqueous 0.1N sodium hydroxide solution are added to each tube. After stirring for about 2 minutes, the aqueous phase is removed; 3 cm3 of water are added and, after stirring for 2 minutes, the aqueous phase is removed and this operation is repeated. The organic phase is dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residues are purified by flash chromatography on a column of silica and the following compounds are obtained:, 216144-45-5
216144-45-5 4-(4-Methylpiperazin-1-yl)benzylamine 2776493, apiperazines compound, is more and more widely used in various fields.
