Reaction Steps

To a solution of 8-hydroxyquinoline-7-carboxylic acid (0.284 g) of Preparation 1 and 2-amino-5-(3-chlorophenyl)-4-hydroxy-1,3-thiazole (0.340 g) in 20 mL DMF is added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.305 g) and 1-hydroxybenzotriazole monohydrate (0.217 g). The mixture is stirred at room temperature for 7 days. The solution is then poured into 30 mL ice-water. The resulting solid is collected and dried. The crude product is triturated with hot EtOAc, then with hot i-PrOH to yield 0.182 g of the title product as a yellow solid.
