1,1'-Thiocarbonyldi-2(1H)-pyridone → 2-Isothiocyanato-6-methoxy-[1,2,4]triazolo[1,5-a]pyridine

Participants

Reaction Steps

To 6-methoxy-[1,2,4]triazolo[1,5-a]pyridin-2-amine (0.3 g, 1.8 mmol) in dichloromethane (15 mL) was added 1,1′-thiocarbonyldi-2(1H)-pyridone (0.51 g, 2.2 mmol). The reaction was stirred at room temperature overnight, concentrated in vacuo and purified via flash chromatography yielding 2-isothiocyanato-6-methoxy-[1,2,4]triazolo[1,5-a]pyridine (166 mg, 0.8 mmol, 44% yield) as a white solid. 1H NMR (300 MHz, CDCl3) δ ppm 8.03 (1 H, d, J=2.20 Hz), 7.54 (1 H, d, J=9.88 Hz), 7.34 (1 H, dd, J=9.51, 2.56 Hz), 3.88 (3 H, s).
