94838-59-2, name is tert-Butyl 4-aminophenethylcarbamate, belongs to amides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. COA of Formula: C13H20N2O2
Tert-butyl (4-aminophenethyl)carbamate (2.33 g, 9.89 mmol, 1.0 eq) was dissolved in DCM (100 mL) and mixed with HBTU (3.75 g, 9.89 mmol, 1.0 eq) and cooled to 0C using an ice bath. Azidoacetic acid (1.0 g, 9.89 mmol, 1.0 eq) was added to the stirring mixture followed by NMM (2.18 mL, 19.79 mmol, 2.0 eq). The mixture was stirred 1 hour at 0C and 23 hours at room temperature. The mixture was then diluted with 0.5 M NaHC03 (100 mL) and the organic phase was separated. The aqueous phase was then extracted two times with 50 mL DCM, the combined organic phases dried over MgS04, filtered and concentrated in vacuo. The crude material was further purified using column chromatography on Si02 with 50-100% EtOAc in heptane as eluent. This gave a pale yellow solid.
The synthetic route of 94838-59-2 has been constantly updated, and we look forward to future research findings.
