120737-78-2, tert-Butyl 2-methylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
51.1: 2-Methyl-4-(1-m-tolyl-1H-[1,2,4]triazole-3-carbonyl)-piperazine-1-carboxylic acid tert-butyl ester 2.00 g (9.84 mmol) 1-m-tolyl-1H-[1,2,4]-triazole-3-carboxylic acid was stirred with 3.30 g (10.3 mmol) TBTU and 2.50 mL (14.6 mmol) DIPEA in 30 mL DCM at RT. After 10 min, 2.05 g (9.84 mmol) 2-methyl-piperazine-1-carboxylic acid tert-butyl ester was added and the reaction mixture was stirred at RT for 12 h. The solvent was removed by distillation. The residue was taken up in water and extracted with EtOAc. The combined organic phases were dried over sodium sulfate, filtered and concentrated in vacuo. The crude material was purified by flash chromatography (EtOAc). Yield: 4.00 g (95%), purity: 90% ESI-MS: m/z=386 (M+H)+ Rt(HPLC): 1.48 min (method 8), 120737-78-2
The synthetic route of 120737-78-2 has been constantly updated, and we look forward to future research findings.
