6-Nitro-4-chloro-2-(3-fluoro-phenyl)-quinoline, 20 g (59.4 mmoles), was placed in a 500 mL three-neck round-bottom flask equipped with magnetic stirrer, nitrogen inlet, gas outlet, condenser and heating bath. The material was dissolved in 150 mL of N-methyl pyrrolidinone, stirred and 250 mL of a 40% aq. solution of dimethylamine was added. The mixture was then warmed to 60° C. for 48 hrs. At the end of this time the reaction was cooled, poured into 3 L of water in a 4 L Erlenmeyer flask and the mixture stirred until solids formed. The solids were collected by vacuum filtration and dried in a vacuum oven. The product was recrystallised from-ethanol in a −20° C. freezer to give 19.6 g (95%) yield of the desired product.
