Electric Literature of 56844-12-3 ,Some common heterocyclic compound, 56844-12-3, molecular formula is C6H2BrClN2S, 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.
General procedure: Compound 1 (1.00 g, 4.01 mmol) was mixed with the benzylamine (12.03 mmol) and 1-butanol (3.5 mL) and agitated at 145 C for 18-24 h. Then the mixture was cooled to rt, diluted with water (50 mL) and diethyl ether (150 mL) or EtOAc (150 mL). After phase separation, the water phase was extracted with more diethyl ether (2 × 50 mL) or EtOAc (2 × 50 mL). The combined organic phases were washed with saturated aq NaCl solution (50 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo, before the crude oil was dried under reduced pressure to constant weight to remove excess benzylamine. The compounds were purified by silica-gel column chromatography or crystallized as specified for each individual compound
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,56844-12-3, its application will become more common.
