Reaction Steps
To a solution of 5-bromo-2-chloropyridine 1-oxide (from step 1) (1.0 eq.) in acetonitrile (0.2 M) was added trimethylsilyl cyanide (TMSCN) (4.0 eq.) and triethylamine (3.0 eq.). The reaction was heated at 100° C. overnight. After cooling to room temperature, the solvent was concentrated en vacuo, and the residue was purified by a COMBIFLASH® system (ISCO) using 0-40% ethyl acetate in hexane to give 3-bromo-6-chloropicolinonitrile.
