Temperatur

110 °C

A mixture of 3-(2,4-dichloro-pyrimidin-5-yl)-2-(4-methoxy-phenyl)-propionic acid methyl ester (0.54 g, 1.58 mmol) (from Example 1d supra) and aniline (0.67 g, 7.11 mmol) (Aldrich) was heated at 110° C. for 30 minutes. The reaction mixture was washed with hexanes (50 mL×3) and the supernatant was decanted off after each time. The residue was then dissolved in ethyl acetate (100 mL) and successively washed with saturated aqueous ammonium chloride solution (30 mL), water (30 mL) and brine (30 mL), dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The crude products was purified by flash column chromatography (silica gel) to give 3-(2,4-diphenylamino-pyrimidin-5-yl)-2-(4-methoxy-phenyl)-propionic acid methyl ester as a white amorphous solid. (Yield 0.49 g, 68.1%).
