Reaction Steps

To 4-bromopicolinic acid (0.3 g, 1.485 mmol) in DMF (4 mL) were added 2-aminoethanol (0.181 g, 2.97 mmol), HOBt (0.301 g, 2.228 mmol), and EDC (0.456 g, 2.376 mmol), followed by N-ethyl-N-isopropylpropan-2-amine (1.293 mL, 7.43 mmol). The reaction mixture was stirred for 18 hours at room temperature. The reaction mixture was diluted with DCM, washed with brine, and concentrated to give the title compound, which was used without further purification.
