Reaktionsschritte

To a solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (0.970 g, 4.17 mmol) in dichloromethane at room temperature was added 6-(3-methoxyphenyl)pyrimidin-4-amine (0.7 g, 3.48 mmol). The reaction was stirred at room temperature for 18 hours. The LC/MS showed the desired product peak as a major peak. The deep orange solution was concentrated and the remaining residue was filtered. The filtrate was purified by silica gel chromatography (0-10% ethyl acetate-hexanes) to afford 4-isothiocyanato-6-(3-methoxyphenyl)pyrimidine (0.39 g, 4.31 mmol, 46% yield) as a yellow oil. LCMS R.T.=2.91; [M+H]+=244.03.
