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., Computed Properties of C14H22N4O4
4-(Dimethylamino)pyridine (660 mg, 5.41 mmol) was added to a solution of tert- butyl(((tert-butoxycarbonyl)imino)(lH-pyrazol-l-yl)methyl)carbamate (11.37 g, 54.1 mmol, 1.0 equiv.) in dichloromethane (60 mL). Di-tert-butyldicarbonate (23.61 g, 108.2 mmol, 2.0 equiv.) in THF (40.0 mL) was slowly added over the course of 8 h using a syringe pump. The solution was stirred overnight at room temperature, before the solvents were removed in vacuo. The resulting colorless solid was stirred in dilute acetic acid solution (0.52 g, 8.66 mmol, acetic acid in 60 mL water). The precipitated tert-butyl tert-butoxycarbonyl(((tert-butoxycarbonyl)imino)( 1 H-pyrazol- 1 -yl)methyl)carbamate was collected, washed with water, hexane, and dried in vacuo to yield a colorless solide (20.21 g, 91% yield).
