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., Safety of tert-Butyl (((tert-butoxycarbonyl)amino)(1H-pyrazol-1-yl)methylene)carbamate
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.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 152120-54-2.
