Versuchsvorschrift

To a mixture of 6-(2-methoxy-phenyl)-pyrimidin-4-ylamine (XXIV) (1.0 g, 4.9 mmol) and potassium carbonate (4.0 g, 29 mmol) in 2-butanone (10 ml), chloroethylformate (0.50 ml, 4.9 mmol) was added and the mixture was refluxed for 3 hours at 80° C. The reaction was monitored by TLC. After completion of the reaction, water was added and the mixture was extracted with ethyl acetate. The organic layer was separated, dried over anhydrous sodium sulfate and concentrated to provide 0.60 g of [6-(2-methoxy-phenyl)-pyrimidin-4-yl]-carbamic acid ethyl ester (XL).
