With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13130-79-5,1-Bromoisoquinolin-3-amine,as a common compound, the synthetic route is as follows.
To a solution of 1-bromoisoquinolin-3-amine (200 mg, 0.897 mmol, Maybridge Chemical Co., Altrincham, UK) in tetrahydrofuran (5 mL) at rt was added sodium bis(trimethylsilyl)amide (1M solution in tetrahydrofuran, 1.79 mL, 1.79 mmol). The mixture was stirred for 10 min before a solution of Boc-anhydride (0.208 mL, 0.897 mmol) in THF (1 mL) was added. The reaction mixture was stirred for 5 min before being diluted with sat. aq. NH4Cl (50 mL) and EtOAc (50 mL). The organic layer was separated, dried over Na2SO4, filtered, and concentrated. Purification by silica gel column chromatography eluting with 0-20% EtOAc in heptane afforded tert-butyl (1-bromoisoquinolin-3-yl)carbamate. m/z (ESI, +ve) 345.0 (M+Na)+.
13130-79-5, As the paragraph descriping shows that 13130-79-5 is playing an increasingly important role.
