Reaction Steps
A solution of 6-hydroxy-8-nitro-quinoline (2.5 g, 13.2 mmol), ethylbromide (1.08 mL, 14.5 mmol), and K2CO3 (4 g, 26.4 mmol) in DMF (50 mL) under a nitrogen atmosphere was heated at 40° C. for 5 hours. The cooled reaction mixture was poured into H2O (200 mL) and extracted into EtOAc (2×200 mL). The organic fractions were combined, dried over NaSO4 and concentrated. The resulting beige solid was triturated with 40% EtOAc/hexane to give 2.46 g (85%) of the title compound as beige crystals.
