87%; 7% | With potassium carbonate; In N,N-dimethyl-formamide; at 20.0℃; for 24.0h; | General procedure: Quinolin-2(1H)-one (1.45 g, 10 mmol), K2CO3(1.38 g, 10 mmol), and dry DMF (50 mL) were stirred at rt for 30 min. To this solution was added 2-bromoacetophenone (1.99 g, 10 mmol) in dry DMF (10 mL) in one portion. The resulting mixture was continued to stir at rt for 24 h (TLC monitoring), and then poured into ice-water (100 mL). The mixture was extracted with CH2Cl2(3×75 mL). The organic layer was combined, washed with H2O, dried (Na2SO4), and then evaporated to give a brown solid which was purified by column chromatography on silica gel (AcOEt/Hexane 1:1). The proper fractions were combined and evaporated to furnish a residual solid which was crystallized from CH2Cl2 /Et2O 1:10 to afford 13a (1.74 g, 66 percent) and 13b (0.17 g, 7 percent). |
