Procedure

Ethyl 5-amino-2-(2-hydroxyphenylamino)-6-(2-methoxyphenylamino)pyrimidine-4-carboxylate. Ethyl 2-(2-hydroxyphenylamino)-6-(2-methoxyphenylamino)-5-nitropyrimidine-4-carboxylate (362 mg, 0.851 mmol) was dissolved in ethanol (20 mL) and 10% palladium on carbon (91 mg, 0.085 mmol) was added. The reaction mixture was stirred at room temperature under an atmosphere of hydrogen overnight. The reaction was then filtered through Celite, solvent was removed under reduced pressure and purified by column chromatography (50% ethyl acetate in hexanes). Fractions containing product were combined and the solvent evaporated to provide the title compound (272.6 mg, 0.689 mmol, 81% yield). MS (ESI) m/z 396.2 [M+1]+.
