Reaction Steps
A solution of 4-chloro-3-nitrobenzoyl chloride (1.539 g, 7.694 mmol) in anhydrous pyridine (40 mL) was treated with 2-amino-5-bromothiazole monohydrobromide (2.00 g, 7.694 mmol), and the reaction stirred under a nitrogen atmosphere at room temperature for 18 hours. The solvent was removed by rotary evaporation in vacuo and the oil dried on hi-vacuum. The residue was taken up in ethyl acetate (150 mL) and washed with water (4×50 mL) and brine (50 mL), then dried the organic phase over anhydrous sodium sulfate, filtered, and concentrated in vacuo. Trituration with 6% ethyl acetate/methylene chloride afforded the title compound as a pinkish-tan solid (1.92 g, 69%).
