Reaction Steps
To methyl 2-oxo-1H-pyridine-4-carboxylate (700 mg, 4.57 mmol) in dry DMF (4.4 mL) was added finely ground K2CO3 (2.53 g, 18.3 mmol) followed by 2-iodopropane (914 μL, 9.14 mmol). The mixture was heated at 60° C. (external) for 1 h. The mixture was diluted with acetonitrile (10 mL) and was filtered. The filtrate was evaporated onto Celite and was purified by column chromatography (0-100% EtOAc/DCM) to give methyl 1-isopropyl-2-oxo-1,2-dihydropyridine-4-carboxylate (230 mg). ESI-MS m/z calc 195.1. found 196.3 (M−1)−. Retention time: 1.09 minutes (3 min run).
