Reaction Steps

A mixture of 6-methylquinoxalin-2-amine 2,2,2-trifluoroacetate (546 mg, 2 mmol), triethylamine (243 mg, 2.400 mmol), and 1,1′-thiocarbonyldipyridin-2(1H)-one (557 mg, 2.40 mmol) was stirred in 5 mL DCM for 4 h. The reaction was directly eluted on a 120 g silica gel cartridge with 0 to 25% EtOAc in hexane, 25 min, at 35 mL/min to afford 2-isothiocyanato-6-methylquinoxaline (153 mg, 0.760 mmol, 38% yield).
