With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.61296-22-8,2-Amino-5-bromothiazole monohydrobromide,as a common compound, the synthetic route is as follows.
B.[00199] To a solution of Part A compound (180 mg, 1.175 mmol) in acetone (5 mL) was added 2-amino-5-bromothiazole monohydrobromide (611 mg, 2.351 mmol) and Cs2CO3 (957 mg, 2.94 mmol). The mixture was stirred at reflux (55 0C) for 18 h, then was cooled to RT and was filtered. The filtrate was concentrated in vacuo. The residue was taken up in EtOAc and was washed with H2O and brine, then was dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by preparative HPLC (Phenomenex Luna AXIA 5u C18 30 x l00 mm column; detection at 220 nm; flow rate = 40 mL/min; continuous gradient from 30% B to 100% B over 10 min + 5 min hold time at 100% B, where A = 90: 10:0.1 H2O:MeOH:TFA and B = 90: 10:0.1 MeOH:H2O:TFA) to give Part B compound (200 mg, 67% yield) as a yellow solid.
61296-22-8 2-Amino-5-bromothiazole monohydrobromide 2723848, athiazole compound, is more and more widely used in various.
