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. 154748-63-7, name is tert-Butyl (3-hydroxycyclobutyl)carbamate, This compound has unique chemical properties. The synthetic route is as follows., HPLC of Formula: C9H17NO3
To a solution of (3-hydroxy-cyclobutyl)-carbamic acid tert-butyl ester (2.5 g, 13.3 mmol) in THF (40 mL) were added CS2CO3 (8.6 g, 26.6 mmol) and 5-bromo-2,4- dichloro- pyrimidine (3 g, 13.3 mmol). The reaction mixture was heated at reflux overnight. The reaction mixture was filtered and concentrated, diluted with EtOAc and water. The aqueous phase was extracted with EtOAc (3 x 100 mL) and the combined organic extracts were washed with brine (60 mL), dried over MgSO*}, filtered, and concentrated. Purification by flash column chromatography on silica gel to give the product (4.75 g, 12.6 mmol, yield: 95%). ESI-MS (M+l): 378 calc. for CisHnBrClNsOs 377.
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 154748-63-7.
