Reaction Steps
A mixture of 4-(6-hydroxyquinolin-2-yl)benzoic acid (Compound 3, Example 3) (200 mg, 0.754 mmol), EDCI (145 mg, 0.754 mmol) and BocNHNH2 (100 mg, 0.754 mmol) in DCM (10 mL) and DMF (10 mL) was stirred at 25° C. overnight, followed by an aqueous/EtOAc workup. The crude was purified by column chromatography on silica gel (PE/EtOAc=1/1) to give the product (200 mg, yield 70%) as a yellow solid.
