2-Bromo-5-nitropyridine CAS 4487-59-6 Application

A mixture of 1.53 g (10.94 mmol) of 2-hydroxy-5-nitropyridine, 4.1 g (12.71 mmol) of tetrabutylammonium bromide and 3.71 g (26.1 mmol) of P2O5 in 29 ml of benzene was heated at reflux Stir for 1 hour. The mixture was cooled to room temperature, the upper layer was separated by decantation, and the lower layer was triturated with benzene (3 x 6 ml). The extracts were combined with the organic phase, washed with a saturated solution of NaHCO3 and NaCl, and dried over MgSO4. The solvent was distilled off under reduced pressure, and the residue was recrystallized from petroleum ether. Yield 1.7g (48%). Mp138-139°C, (bp40-70°C).
