A mixture of 8-bromoquinolin-2(1H)-one (5 g, 22 mmol) and phosphoryl tribromide (13 g, 45 mmol) was heated to 140° C. for three hours. The resulting mixture was poured onto 100 g of ice and 100 ml water. The mixture was stirred for 1 hour and the resulting solids were filtered to yield the title compound. (5.1 g, 80% yield) MS APCI (+) 286, 288, and 290 (M+1 of each isotope combination) detected.
