To a solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (0.682 g, 2.94 mmol) in dichloromethane/N,N-dimethylformamide at room temperature was added 6-(pyridin-3-yl)pyrimidin-4-amine (0.337 g, 1.957 mmol). The 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 (1-40% ethyl acetate-hexanes) to afford 4-isothiocyanato-6-methoxypyrimidine (0.12 g, 0.56 mmol, 28.6% yield) as an orange oil.
