31166-44-6, 1-Cbz-Piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of tert-butyl 2,4-dichloro-8-oxo-5,8-dihydropyrido[3,4-d]pyrimidine-7(6H)-carboxylate (0.400 g, 1.26 mmol) in CH 2Cl 2 (5.0 mL) was added N,N-Diisopropylethylamine (0.325 g, 2.51 mmol) followed by benzyl 1-piperazinecarboxylate (0.255 mL, 1.32 mmol) and the reaction stirred at ambient temperature for 1.5 h. The reaction mixture was diluted with CH 2Cl 2 (10 mL) and washed with a 0.5M KHSO 4 solution (5 mL), followed by a saturated aqueous NaHCO 3 solution and brine. The organic layer was dried over Na 2SO 4, filtered and concentrated. The crude product was sonicated in 10 mL MTBE and the resulting solid was isolated by vacuum filtration. The solid was dried in vacuo to provide 0.507 g (80%) of the desired product as an off-white solid which was used directly in the next step. ES+APCI MS m/z 502.1[M+H] +.
31166-44-6, The synthetic route of 31166-44-6 has been constantly updated, and we look forward to future research findings.
