Reaction Steps

A solution of pyridine (0.13 mL, 1.6 mmol) and ethyl bromopyruvate (0.22 mL, 1.7 mmol) in EtOH (0.5 mL) was stirred at 70° C. in a sealed vial for 16 h. The reaction mixture was allowed to cool to ambient temperature and a solution of 2-amino-6-bromonicotinaldehyde (317 mg, 1.58 mmol) and pyridine (0.76 mL, 9.5 mmol) in EtOH (1 mL) was added. The reaction mixture then was heated at 100° C. in a sealed vial for 16 h. Pyrrolidine (0.26 mL, 3.2 mmol) was added, and stirring in the sealed vial was continued at 100° C. i for 16 h. The crude reaction mixture was purified by flash chromatography (40 g silica gel column, eluting with 0-100% EtOAc/hexanes) to afford the sub-title compound. LCMS (ESI) calc. for C13H16N3O3 [M+H]+: m/z=262.1. found: 262.0.
