Versuchsvorschrift

Ethyl 5-amino-2-(4-hydroxyphenylamino)-6-(2-methoxyphenylamino)pyrimidine-4-carboxylate. Ethyl 2-(4-hydroxyphenylamino)-6-(2-methoxyphenylamino)-5-nitropyrimidine-4-carboxylate (220 mg, 0.517 mmol) was dissolved in ethanol (10 mL) and 10% palladium on carbon (55 mg, 0.052 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 (60-100% ethyl acetate in hexanes). Fractions containing product were combined and the solvent evaporated to provide the title compound (201.3 mg, 0.509 mmol, 98% yield). MS (ESI) m/z 396.2 [M+1]+.
