Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 239074-29-4, name is tert-Butyl (trans-4-(hydroxymethyl)cyclohexyl)carbamate, A new synthetic method of this compound is introduced below., 239074-29-4
To a solution of tert-butyl [trans-4-(hydroxymethyl)cyclohexyl]carbamate (0.50 g, 2.2 mmol) (Supplier: Chem-Impex) in methylene chloride (15 mL) was added triethylamine (1.29 mL, 9.27 mmol), 4-dimethylaminopyridine (53 mg, 0.44 mmol), and p-toluenesulfonyl chloride (0.89 g, 4.7 mmol). The resulting mixture was stirred at room temperature for 2 h before adding more p-toluenesulfonyl chloride (0.42 g, 2.2 mmol). The mixture was stirred overnight. Water and dichloromethane were added and the layers separated. The aqueous was extracted with dichloromethane. The combined organics were washed with water and brine, dried (MgSO4), filtered, and concentrated. The residue was purified on Biotage Isolera (40 g Agela cartridge, eluted with 5-50% EtOAc/hexanes over 15 min) to give the desired product (0.72 g, 86%) as a white crystalline solid. LCMS calculated for C19H29NO5SNa (M+Na)+: m/z=406.2. Found: 406.0.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
