Reaction Steps

The product from Step 2 (3.0 g) and potassium carbonate (1.6 g) were stirred in dry DMF (100 ml) at 100° C. for 3 hours. The reaction was cooled and the excess DMF evaporated to give a black oil. Water (100 ml) was added and then washed with ethyl acetate. The aqueous fraction was filtered and acidified with 2M aqueous hydrochloric acid to neutral pH, and the water was evaporated to give a solid, which was then extracted with methanol. The methanol extract was evaporated to give the crude 3-(2,4,6-trifluorophenyl)-1H-[1,7]naphthyridine-2,4-dione as a dark brown crystalline solid (2.0 g), which was used for the next reaction without further purification.
