With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.111600-83-0,5-Bromo-4-methylthiazole,as a common compound, the synthetic route is as follows.
Compound 47b (300 mg, 1.69 mmol) under nitrogen,B2pin2 (861 mg, 3.39 mmol), Pd(dppf)Cl2 (30 mg, 0.04 mmol) and KOAc (332 mg, 3.39 mmol) were placed in a reaction flask.Add 20mL of ethylene glycol dimethyl ether,Heat to 80 C for 8 h.After the reaction was cooled to room temperature, filtered and the filtrate washed with water, EtOAc. The combined organic phase was dried over anhydrous sodium sulfate, filtered and the solvent was distilled off under reduced pressure, purified by silica gel column chromatography to give compound 47c (400mg).
111600-83-0, As the paragraph descriping shows that 111600-83-0 is playing an increasingly important role.
