Reaction Conditions:
with bromine;acetic acid at 0 - 30; for 2 h;
Steps:
5.a
(a)at 0 ° C2-Aminothiazole (400 mg, 4 mmol) was dissolved in 16 mLAcetic acid solution,Bromine (408 μL, 8 mmol) was slowly added dropwise.The mixture was further stirred at room temperature for 2 hours,TLC reaction was monitored until the reaction was completed,The pH was adjusted to 7-8 with saturated NaHCO3,Ethyl acetate (20 mL x 3), washed with saturated saline and the organic layer was mixed,Dry over anhydrous sodium sulfate, filter and concentrate and purify by column chromatography5-Bromothiazol-2-amine(520 mg, 75% yield).
