실험 절차

Acetic 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 (10 g; 1.81 mmol) (from Example 3c supra) was dissolved in a mixture of methanol (17 mL) and water (7 mL) and treated with potassium carbonate (1.00 g; 7.26 mmol) at room temperature for 19 hours. The reaction mixture was partitioned between ethyl acetate and water-brine mixture. The organic phase was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. The crude material was purified by flash chromatography (Biotage 40M; ethyl acetate) to give (±)-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. (Yield 0.67 g; 72.9%). A small amount of additional material bumped over into the solvent trap during concentration. This material was recovered and crystallized from ethyl acetate. (Yield 0.09 g; 9.9%). Melting Point: 195–200° C. HR-MS(ES+) m/z Calculated for C29H26N6O3 ([M+H]+): 507.2139. Found: 507.2145. HR-MS(ES+) m/z Calculated for C29H26N6O3 ([M+Na]+): 529.9158. Found: 529.1963.
