Procedure

Bromine (29 ml, 560 mmol) was added to a stirred solution of 2-oxo-1,2-dihydro-pyridine-3-carbonitrile (34 g, 280 mmol) in acetic acid (180 ml) at room temperature. After 14 hours the reaction mixture was concentrated in vacuo and the resulting oil was trituated with ethanol to afford the title compound as a solid.
