To a bright orange solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (0.486 g, 2.091 mmol) in dichloromethane/N,N-dimethylformamide at room temperature was added 6-(3-chlorophenyl)pyrimidin-4-amine (0.43 g, 2.091 mmol). The orange mixture was heated at 60° C. for 18 hours. The LC/MS showed the desired product peak as a major peak. The deep orange mixture was purified by silica gel chromatography (0-40% ethyl acetate-hexanes) to afford 4-(3-chlorophenyl)-6-isothiocyanatopyrimidine (0.12 g, 0.484 mmol, 23% yield) as an orange oil. LCMS R.T.=2.15; [M]+=248.31.
