With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.38216-72-7,1-tert-Butylpiperazine,as a common compound, the synthetic route is as follows.
A. Synthesis of l-(4-(4-fert-butylpiperazin-l-yl)(phenyl)methyl)piperidin-l-yl)ethanone; [0092] 1-tert-butylpiperazine (4.48 g, 20.8 mmol), l-(4-(chloro(phenyl)methyl)piperidin-l-yl)ethanone (5.77 g, 22.9 mmol), K2CO3 (7.2 g, 52.1 mmol), and KI (22.9 mmol) were combined in dry DMF (150 mL). The reaction was refluxed overnight. Upon completion of the reaction, the DMF was removed under reduced pressure. The resulting crude was taken up in water (75 mL) and washed with EtOAc (3 x 100 mL). The organic portions were combined, dried (Na2SO4) and concentrated. The product was purified by silica gel chromatography (2.5:2.5:95 Et3N/MeOH/EtOAc, Rf 0.4) and isolated as a red oil (2.66 g, 36%).
38216-72-7, 38216-72-7 1-tert-Butylpiperazine 3530572, apiperazines compound, is more and more widely used in various fields.
