Reaction Steps
60 g (0.27 mol) of 2-chloro-1-nitro-5-trifluoromethylbenzene, 50 g (0.56 mol) of β-alanine and 41 g (0.3 mol) of potassium carbonate were refluxed in a mixture of 300 ml of dimethylformamide and 50 ml of water for 6 h. The mixture was then poured into ice-water, the aqueous phase was acidified with hydrochloric acid, and the precipitate was filtered off with suction to yield 73 g (99%) of the product.
