Versuchsvorschrift

(±)-3-[7-[3-(2-Hydroxy-ethyl)-phenylamino]-3-(4-methoxy-phenyl)-4-methyl-2-oxo-3,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-1-yl]-benzonitrile (0.67 mg; 1.27 mmol) (from Example 4 supra) was suspended in dichloromethane (13 mL). The mixture was treated with triethylamine (0.23 mL; 1.65 mmol) and methane-sulfonyl chloride (0.13 mL; 1.68 mmol) (Aldrich). The solid went into solution as the methanesulfonyl chloride was added. After 45 minutes, the reaction was shown by thin layer chromatography to be complete. The reaction was diluted with additional dichloromethane and washed with water and then brine. The organic phase was dried over anhydrous sodium sulfate, concentrated and dried under high vacuum to give crude (±)-methanesulfonic acid (2-{3-[8-(3-cyano-phenyl)-6-(4-methoxy-phenyl)-5-methyl-7-oxo-5,6,7,8-tetrahydro-pyrimido[4,5-d]pyrimidin-2-ylamino]-phenyl}-ethyl)-ester as a foam. This material was used in the next step without further purification. (Yield: 0.76 g, 95.4%).
