Synthetic Route of 31462-58-5 ,Some common heterocyclic compound, 31462-58-5, molecular formula is C4H3IN2, its 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.
Zinc powder (0.12 g, 1.8 mmol) was added to a dry flask purged with nitrogen. Dry DMF (1.0 ml) was added followed by iodine (43 mg, 0.2 mmol). The solution changed from colourless to yellow and then back to colourless. Methyl (2S)-2-{[(tert-butoxy)carbonyl]amino}-3- lodopropanoate (0.20 g, 0.60 mmol) was added, followed by iodine (43 mg, 0.2 mmol). The solution was stirred at ambient temperature, with an exotherm observed. To this solution was added Pd2(dba)3(28 mg, 0.04 mmol), SPhos (24 mg, 0.12 mmol) and 5-iodopyrimidine (0.33 g, 1.6 mmol). The RM was stirred at rt under nitrogen for 18 h. The RM was filtered twice and then purified by FCC (silica, EtOAc / hexane) to give the desired product. Y = 80 %MS ES+: 282
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,31462-58-5, its application will become more common.
