Versuchsvorschrift
A solution of 3-bromo-6-oxo-1,6-dihydropyridine-2-carbonitrile (from Example 15/Step 2) (1.0 eq.), silver carbonate (1.3 eq.), and iodomethane (1.2 eq.) in toluene (0.2 M) was stirred in the dark at room temperature overnight. The solvent was concentrated en vacuo, and the resulting residue was purified by a COMBIFLASH® system (ISCO) using 0-80% ethyl acetate in hexane to give 3-bromo-6-methoxypicolinonitrile.
