Synthetic Route of 152120-54-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 152120-54-2, name is tert-Butyl (((tert-butoxycarbonyl)amino)(1H-pyrazol-1-yl)methylene)carbamate, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Diisopropyl azodicarboxylate (DIAD, 1.5 equiv) was added dropwise to a stirred solution of alcohol 1a-g (1-2 equiv), N,N?-bis-tert-butoxycarbonylpyrazole-1H-carboxamidine 2 (2.5 mmol, 1 equiv), and Ph3P (1.5 equiv) in THF (7 mL) at 0 C. The reaction mixture was stirred overnight (16 h) at r.t., concentrated in vacuum, and the residue was purified by flash column chromatography on silica gel (10-25% EtOAc-hexane) to give the N-alkylated guanylating agent 3a-g as colorless oils.
The chemical industry reduces the impact on the environment during synthesis tert-Butyl (((tert-butoxycarbonyl)amino)(1H-pyrazol-1-yl)methylene)carbamate. I believe this compound will play a more active role in future production and life.
