Some common heterocyclic compound, 147291-66-5, name is tert-Butyl 3-aminobenzylcarbamate, molecular formula is C12H18N2O2, 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 3-aminobenzylcarbamate
a) fert-Butyl 3-((7-chloro-5-hydroxy-1 ,1 -dioxido-2H-benzo[e][1 ,2,4]thiadiazin-3- yl)amino)benzylcarbamate (3107) To a stirred solution of 3-bromo-7-chloro-5-hydroxy-2H-benzo[e][1 ,2,4]thiadiazine 1 ,1 – dioxide (lnt-3, 400 mg) in fe/f-butanol (15 mL) at room temperature in a sealed tube were added fe/ -butyl 3-aminobenzylcarbamate (342 mg) and potassium dihydrogenphosphate (210 mg). The reaction mixture was warmed to 100 C for 16 h. The reaction mixture was cooled to room temperature and diluted with cold water. The solids were collected by filtration and dried under reduced pressure. The solids were triturated with diethyl ether and pentane to afford titled compound (250 mg) as an off-white solid. LCMS 396.98 m/z (M+H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 147291-66-5, its application will become more common.
