N-bromobutanimide → 6-BROMO-8-FLUORO-3,4-DIHYDROQUINOLIN-2(1H)-ONE

Participants

Reaction Steps

To a stirred solution of 8-fluoro-3,4-dihydroquinolin-2(1H)-one (109-2; 7 g, 0.0424 mol) in N,N-dimethylformamide (30 mL) was added N-bromosuccinimide (9.06 g, 0.050 mol) portion wise at 0° C. Reaction mixture was allowed to stir at room temperature for 12 h. The reaction mixture was concentrated and diluted with ice cold water (150 mL) with constant stirring and the solid residue was filtered and dried to obtain the title compound. MS (M+1): 245.1
