Some common heterocyclic compound, 94838-59-2, name is tert-Butyl 4-aminophenethylcarbamate, molecular formula is C13H20N2O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 94838-59-2
Z-Phe-Cit (9.13 g, 20 mmol) was charged into a mixture of dichloromethane (750 mL) and isopropanol (250 mL) and then stirred until the dipeptide was completely dissolved. Then, APEA-Boc (7.09 g, 30 mmol) and EEDQ (7.42 g, 30 mmol) were added and the mixture was stirred at room temperature for 3 days. The solvents were removed under reduced pressure and then diethyl ether (300 mL) was added to the residue. The mixture was filtered off and the crude product was re-suspended in diethyl ether (300 mL). This procedure was repeated 3 times. The collected solid product was finally dried under vacuum to afford Z-Phe-Cit-APEA-Boc (9.53 g, yield 70.6%). The product was characterized by PMR.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 94838-59-2, its application will become more common.
