実験手順

A mixture of 2-(2,6-dichloro-phenyl)-3-(2,4-dichloro-pyrimidin-5-yl)-propionic acid methyl ester (0.20 g, 0.53 mmol) (from Example 2a supra) and aniline (2.0 ml) (Aldrich) was heated at 110° C. for 2 hours. 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 to give the crude 3-(2,4-diphenylamino-pyrimidin-5-yl)-2-(2,6-dichloro-phenyl)-propionic acid methyl ester as a brown caramel which was used in the next step without further purification. (Yield 0.18 g, 69.3%).
