Reaction Steps

6-Bromo-3-nitro-quinolin-4-ol (Fluorochem Ltd., Derbyshire, UK, 10 g, 37.2 mmol) was added to POCl3 (70 ml). The RM was stirred at 120° C. for 17 h. Then the RM was cooled with an ice-bath, before being slowly dropped onto ice-water. The precipitate was filtered and washed with cold water. The residue was dissolved in DCM, washed with brine, dried over Na2SO4, filtered and evaporated to give the title compound as a beige solid (HPLC tR 3.64 min (Method A))
