Ammonium nitrate → HCID 66982354, compound

Participants

Reaction Steps

To a solution of 150 mg of t-butyl 1-(3-methoxypropyl)-2-oxo-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate in 4.2 ml of acetonitrile were added 107 mg of N-bromosuccinimide and 3.7 mg of ammonium nitrate, followed by stirring at room temperature for 3.5 hours. The reaction mixture was concentrated to about ¼, and ethyl acetate, an aqueous sodium thiosulfate solution, and aqueous sodium bicarbonate was added thereto. The organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate. The solvent was evaporated to obtain 198 mg of t-butyl 11-bromo-1-(3-methoxypropyl)-2-oxo-1,2,3,4,6,7,9,10-octahydro-8H-azepino[4,5-g]quinoline-8-carboxylate.
