With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.259808-67-8,1-Boc-3,3-Dimethylpiperazine,as a common compound, the synthetic route is as follows.
Intermediate 28 : (2,2-Dimethyl-piperazin- lyl)-[ 1 -(3-fluoro-phenyl)- 1Eta-[ 1 ,2,4]triazol-3yl]- methanone A mixture of 460 mg (2.22 mmol) l-(3-fluoro-phenyl)-lH-[l,2,4]triazole-3-carboxylic acid and 330 (2.49 mmol) l-chloro-N,N,2-trimethylpropylamine in 10 mL THF was stirred at RT for 30 min, 500 mg (2.22 mmol) 3,3-dimethyl-piperazine-l-carboxylic acid tert-butyl ester and 620 (4.45 mmol) TEA were added and the mixture was stirred at RT for 1 h. The solvent was removed by distillation and the residue was purified by HPLC. yield: 205 mg (30 %) ESI-MS: m/z = 304 (M+H)+ Rt(HPLC) : 1.24 min (method 3), 259808-67-8
259808-67-8 1-Boc-3,3-Dimethylpiperazine 22710387, apiperazines compound, is more and more widely used in various fields.
