実験手順

To a solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (0.601 g, 2.59 mmol) in dichloromethane/N,N-dimethylformamide at room temperature was added 6-(pyridin-4-yl)pyrimidin-4-amine (0.297 g, 1.725 mmol). The orange mixture was heated at 60° C. for 18 hours. LC/MS showed the desired product peak as the major peak. The deep orange mixture was purified by silica gel chromatography (0-40% ethyl acetate-hexanes) to afford 4-isothiocyanato-6-(pyridin-4-yl)pyrimidine (0.055 g, 0.257 mmol, 15% yield) as an orange solid. LCMS R.T.=1.46; [M+H]+=215.09.
