Reaction Steps

2-(Pyridin-2-yl)ethanol (7.2 g, 58 mmol) and thionyl chloride (10.6 g, 89.1 mmol) were combined in THF (30 mL) and heated at reflux for 16 h. Upon cooling, the solid was filtered off and washed with THF to provide the title compound (4.2 g, 40%) as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 8.82 (d, J=5.6 Hz, 1H), 8.51-8.45 (dt, J=7.8, 1.5 Hz, 1H), 8.00 (d, J=7.9 Hz, 1H), 7.91-7.86 (m, 1H), 4.14 (t, J=6.5 Hz, 2H), 3.53 (t, J=6.5 Hz, 2H).
