Reaction Steps

According to Scheme 1 Method B: 3-Methoxyaniline (1.62 mmol, 0.18 mL) was added to a solution of picolinic acid (1.62 mmol, 0.20 g), EDCI.HCl (2.44 mmol, 0.47 g), Et3N (3.25 mmol, 0.45 mL), hydroxybenzotriazole (1.95 mmol, 0.30 g) in DCM (6 mL) at room temperature. The reaction mixture was stirred at 50° C. for 12 hours. The organic phase was washed with a saturated solution of NaHCO3 and with brine, was dried over MgSO4, was filtered and was concentrated under reduced pressure. The crude product was purified by flash chromatography over silica gel using cyclohexane/AcOEt (90:10) as eluent to afford N-(3-methoxyphenyl)picolinamide (1.46 mmol, 0.33 g, 90%) as an orange liquid.
