According to Scheme 2: K2CO3 (2.33 mmol, 323 mg) and 2-bromo-1-(2-methoxyphenyl)ethanone (0.47 mmol, 107 mg) were added sequentially to a solution of N-(3-hydroxyphenyl)picolinamide (0.47 mmol, 100 mg) in acetone (3 mL). The reaction mixture was stirred at 50° C. for 14 hours. After filtration and evaporation, the crude product was diluted with water and with DCM. The organic phase was washed with brine, was dried over MgSO4, was filtered and was concentrated under reduced pressure. The crude product was triturated with Et2O to obtain N-(3-(2-(2-methoxyphenyl)-2-oxoethoxy)phenyl)picolinamide (0.26 mmol, 94 mg, 55%) as a yellow solid.
