Reaction Steps

A mixture of 3,6-dichloropyridin-2-amine (0.772 g, 4.74 mmol), sodium carbonate (2.01 g, 18.9 mmol), and thiophosgene (0.726 mL, 9.47 mmol) in 6 mL DCM was heated to 55° C. in a sealed tube for 36 h. The reaction was filtered through a frit, rinsing with DCM, and the material was adsorbed onto 6 g silica gel and dried. The material was purified by silica gel chromatography, 40 g, 0-100% EA/hexanes to give 3,6-dichloro-2-isothiocyanatopyridine. 1H NMR (400 MHz, DMSO-d6) 8 ppm 8.19 (d, J=8.5 Hz, 1 H), 7.59 (d, J=9.5 Hz, 1 H).
