Reaction Steps

2-Aminothiazole (100 mmol) was suspended in 1,2-dichloroethane (200 mL) and pyridine (100 mmol) was added. The mixture was added portion wise to a suspension of 4-nitro benzoic acid chloride (150 mmol) in 1,2-dichloroethane (500 mL) and stirred at 60° C. over night. The reaction mixture was cooled and filtered. The filtrate was washed with 1,2-dichloroethane and dried in vacuo to give 4-nitro-N-thiazol-2-yl-benzamide.
