N-bromobutanimide → 6-Amino-7-bromo-quinoline-5-carboxylic acid methyl ester

Participants

Reaction Steps

To a mixture of 6.6 g (32.6 mmol) of 6-amino-quinoline-5-carboxylic acid methyl ester, prepared as in step b in example 45, in 50 mL of N,N-dimethylformamide is added 5.80 g (17.78 mmol) of N-bromosuccinimide. The reaction is stirred at ambient temperature for 4 hours. The solvent is then evaporated and the residue is submitted to column chromatography purification on silica gel with ethyl acetate as eluent to afford 1.59 g (17%) of the product as a yellow solid; LC/MS:281/283 (M+H)+.
