Procedure
5-(Methoxycarbonyl)pyridine-2-carboxylic acid (758 mg, 4.18 mmol) was dissolved in DMF (25 mL) and morpholine (603 uL, 5.23 mmol), Et3N (2.45 mL, 16.7 mmol) and HBTU (1.67 g, 4.39 mmol) were added. The reaction mixture was stirred for 16 h and concentrated in vacuo. The residue was dissolved in EtOAc (100 mL), washed with sat aq Na2CO3 (100 mL), dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography to give the title compound (914 mg, 87.3%) as a yellow oil. LCMS (ES+): 251.2 [MH]+.
