Reaction Steps

A solution of 4-bromo-2,6-bis-(2,2,2-trifluoro-ethyl)-pyridine 1-oxide (2.1 g, 6.2 mmol) and PBr3 (1 mL) in CH2Cl2 (15 mL) was stirred at room temperature for 4 hours. The reaction mixture was poured into ice, made basic with 15% NaOH and extracted with EtOAc. The organic layers were washed with brine, dried over Na2SO4 and concentrated to a pale yellow solid (1.77 g, 89%). 1H NMR (400 MHz, CDCl3): δ 3.59 (t, J=10.4 Hz, 4 H), 7.51 (s, 2 H).
