1,1'-Thiocarbonyldi-2(1H)-pyridone → HCID 86649894, compound

Participants

Reaction Steps

Step E (4): Dichloromethane (25 mL) was added to a flask charged with 4-(3-chloro-1H-1,2,4-triazol-1-yl)-3-methoxyaniline (0.577 g, 2.57 mmol) and 1,1′-thiocarbonyldi-2(1H)-pyridone (0.597 g, 2.57 mmol). The resulting mixture was stirred for 24 h at rt. The crude reaction mixture concentrated in vacuo and the crude product was purified using silica gel chromatography (0-5% EtOAc/chloroform, linear gradient) to afford 3-chloro-1-(4-isothiocyanato-2-methoxyphenyl)-1H-1,2,4-triazole (529 mg, 1.983 mmol, 77% yield) as a off-white solid. LC-MS (M+H)+ 267.1. 1H NMR (500 MHz, chloroform-d) δ ppm 8.67 (s, 1 H) 7.79 (d, J=8.55 Hz, 1 H) 6.98 (dd, J=8.70, 1.98 Hz, 1 H) 6.91 (d, J=1.83 Hz, 1 H) 3.97 (s, 3 H).
