実験手順
To a mixture of 2-amino-4-hydroxyquinoline (0.505 g, 3.15 mmol) and K2CO3 (0.87 g, 6.3 mmol) in DMF (10 mL) was added of 2-bromoethanol (0.470 g, 3.78 mmol). The mixture was stirred at 150° C. for 7 h. The reaction mixture was concentrated and the residue purified by column chromatography on silica using MeOH/CHCl3 (1:9) as eluent. The resulting brown oil (0.30 g, 30%), which was used directly in the next step, contained 75% of the desired product and 25% of unreacted starting material. MS m/z 205 (M+H)+.
