Procedure

A mixture of 3-(2-chloro-4-phenylamino-pyrimidin-5-yl)-2-(4-methoxy-phenyl)-propionic acid methyl ester (40 mg, 0.1 mmol) (from Example 12b supra) and 5-amino-2-methoxypyridine (37.2 mg, 0.3 mmol) (Aldrich) was heated at 110° C. for 4 hours. After cooling, the reaction mixture was diluted with ethyl acetate (50 mL) and successively washed with saturated aqueous ammonium chloride solution (10 mL), water (10 mL) and brine (10 mL), dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give crude 3-[2-(6-methoxy-pyridin-3-ylamino)-4-phenylamino-pyrimidin-5-yl]-2-(4-methoxy-phenyl)-propionic acid methyl ester as a dark-red solid which was used in the next step without further purification. (Yield 47.1 mg, 96.8%).
