171504-98-6, Methyl 1,4-Bis(Boc)-2-piperazinecarboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Step 1: (0892) To a solution of DIPA (3.67 g, 36 mmol, 1.2 eq) in THF (18 mL) was added n-BuLi (2M, 18 mL, 1.2 eq) dropwise at -78 C. over 15 min and the mixture was stirred for another 15 min at -78 C. Then compound AH (10.3 g, 30 mmol, 1.0 eq) in THF (30 mL) was added dropwise to the reaction at -78 C., after the addition was completed, the mixture was stirred for another 30 min at -78 C. BOMC1 (7 g, 45 mmol) in THF (20 mL) was added dropwise over 20 min at -78 C., the reaction mixture was stirred for 16 h and the temperature was warmed to rt during this period. The reaction was quenched with 1M HCl (50 mL), extracted with EA (100 mL) two times, the organic layer was dried and concentrated, the residue was purified on silica gel (EA/PE: 0%-20%) to give compound 90-C-1 as colorless oil (8.2 g)., 171504-98-6

The synthetic route of 171504-98-6 has been constantly updated, and we look forward to future research findings.
