Analyzing the synthesis route of tert-Butyl 4-(4-aminobenzoyl)piperazine-1-carboxylate

350684-49-0, tert-Butyl 4-(4-aminobenzoyl)piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

tert-Butyl 4-(4-aminobenzoyl)piperazine-1-carboxylate (4.98mmol, 1.52Og) was dissolved in dichloromethane and trifluoroacetic acid added. The reaction was left overnight and then treated to SCX purification. The intermediate amine was combined with 2-(4-(bromomethyl)phenyl)-1 ,1 ,1 ,3,3,3-hexafluoropropan-2-ol (4.98mmol, 1.678g) and potassium carbonate (4.98mmol, 0.688g) in acetonitrile (3OmL) and stirred overnight. The reaction was concentrated under reduced pressure and the residue partitioned between water and ethyl acetate. The organic layer was separated and concentrated under reduced pressure. Purification by SCX column chromatography and silica chromatography (eluting with ethyl acetate) gave the title compound (1.25g). MS (ESI) m/z 462.5 [M+H]+

350684-49-0, The synthetic route of 350684-49-0 has been constantly updated, and we look forward to future research findings.
