Procedure
Step J (3): Dichloromethane (15 mL) was added to a flask charged with a 1:1 mixture of 4-(4-chloro-1H-imidazol-1-yl)-3,5-difluoroaniline/3,5-difluoro-4-(1H-imidazol-1-yl)aniline (1.0 g, 4.36 mmol) and 1,1′-thiocarbonyldipyridin-2(1H)-one (1.012 g, 4.36 mmol). The resulting mixture was stirred for 16 h at rt. The crude reaction mixture was concentrated and the crude products were purified using silica gel chromatography (60% EtOAc/hexanes) to afford 4-chloro-1-(2,6-difluoro-4-isothiocyanatophenyl)-1H-imidazole (195 mg, 0.718 mmol, 17% yield). LC-MS (M+H)+ 272.0. 1H NMR (500 MHz, chloroform-d) δ ppm 7.57 (d, J=1.83 Hz, 1 H) 7.07 (d, J=1.53 Hz, 1 H) 6.94-7.04 (m, 2 H).
