Reaction Steps

Potassium (6-bromopyridin-2-yl)(hydroxy)acetate (423 mg, 1.57 mmol), HOBT (600 mg, 3.91 mmol), EDC (750 mg, 3.91 mmol), and methylamine hydrochloride (529 mg, 7.83 mmol) were taken up in DMF (5.0 mL), and DIEA (684 μL, 3.91 mmol) was added. The reaction was stirred at room temperature for 6 hours, diluted with water, and extracted with 5:1 CH2Cl2:MeOH (2×). The combined organic layers were dried over MgSO4, filtered, and evaporated. Silica gel chromatography (40-100% EtOAc/hexanes) provided the title compound as a colorless solid.
