Some common heterocyclic compound, 744183-20-8, name is tert-Butyl exo-3-amino-8-azabicyclo[3.2.1]octane-8-carboxylate, molecular formula is C12H22N2O2, 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: tert-Butyl exo-3-amino-8-azabicyclo[3.2.1]octane-8-carboxylate
A solution of 5,7-dichloro-3-iodo-1,6-naphthyridine (7.0 g, 21.6 mol), DIPEA (5.6 g, 43.2 mmol) and tert-butyl (1R,3s,55)-3-amino-8-azabicyclo[3 .2.11 octane-8-carboxylate(5.8 g, 25.9 mmol) dissolved in NMP (70 mL) was heated at 110C for 3 h. The reaction mixture was purified by column chromatography (eluted with EtOAc:petroleum ether 0- 20 %) to give the title intermediate as ayellow solid (10.2 g, 91.8 % yield).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 744183-20-8, its application will become more common.
