Application of 38336-04-8,Some common heterocyclic compound, 38336-04-8, name is 2-(Benzyloxy)-1-ethanamine, molecular formula is C9H13NO, 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.
To a solution of tert-butyl 4-((6-bromopyridin-3-yl)oxy)piperidine-1-carboxylate (200 mg, 0.280 mmol), 2-(benzyloxy)ethanamine (50.8 mg, 0.336 mmol), sodium 2-methylpropan-2-olate (81 mg, 0.840 mmol), and 2-(dicyclohexylphosphino)-2?,4?,6?-triisopropylbiphenyl (13.34 mg, 0.028 mmol) in THF (5 mL) was added tris(dibenzylideneacetone)dipalladium(0) (25.6 mg, 0.028 mmol). The reaction mixture was stirred at 70 C. for 15 h before cooling to RT and partitioning with water (10 mL) and EtOAc (10 mL¡Á3). The combined organic layers were washed with water (20 mL¡Á3), dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by prep-TLC (1/1 EtOAc/petroleum ether) to provide the title compound.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(Benzyloxy)-1-ethanamine, its application will become more common.
