57260-71-6, tert-Butyl piperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,57260-71-6
Synthesis of 4-(4-formyl-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (1). A mixture of 4-(tert-butyl-l -piperazinecarboxylate (556 mg, 3.0 mmol), 4- fluoro-benzaldehyde (315 mul, 3.0 mmol) and K2CO3 (514 mg, 3.7 mmol) in DMF (5 ml) was stirred at ambient temperature overnight. Reaction was diluted with water (30 ml) and extracted with EtOAc (50 ml x 2). Organic layer was washed with water (20 ml), 1 M aq. HCl (20 ml), water (20 ml x 2) and brine (20 ml) and dried over MgSO4 (anh.). Solvent was evaporated in vacuum. Residue was triturated with hexane. Formed precipitate was filtrated and dried in vacuum overnight to provide target compound (1) (342 mg, 39%) as off-white solid. LC-MS [M+H] 291.2 (C16H22N2O3+H, requires 291.38).
The synthetic route of 57260-71-6 has been constantly updated, and we look forward to future research findings.
