Example 104 Synthesis of 6-Chloro-N,N’-bis-(3fluoro-4-methoxy-phenyl)-[1,3,5]triazine-2,4-diamine (E15) To 124 (1.09 g, 3.5 mmol) dissolved in acetone (25 mL) was added 3-fluoro-p-anisidine (0.54 g, 3.5 mmol) in acetone (5 mL) followed by addition of 2.5 N NaOH (1.4 mL, 3.5 mmol) and water (3.5 mL). The reaction mixture was stirred and heated at reflux for 3 hours. The reaction mixture was extracted three times using dichloromethane; the combined organic layers were washed with brine and dried over potassium carbonate. The sample was filtered, concentrated in vacuo, and the resulting solid was dried overnight under vacuum to yield white solid (E15) (1.332 g, 97percent); mp 194¡ã C.; HPLC: Inertsil ODS 3V C18, 40:30:30 v:v:v [KH2PO4 (0.01 M, pH 3.2):CH3OH:CH3CN], 264 nm, Rt 33.2 min, 97.6percent purity; MS (TOF ES+) m/z 396 (35.0); 394 (M+H, 100).
