Procedure

To cyanuric chloride (36.911 g, 200.0 mmol) dissolved in acetone (250 mL) stirring at approximately 0–5° C. (ice-water bath), was added a solution of 3-chloro-p-anisidine (31.528 g, 200.0 mmol) in acetone (150 mL) followed by the addition of NaOH solution (80 mL, 2.5 N, 200.0 mmol). The reaction mixture was allowed to stir at approximately 0–5° C. (ice-water bath) for about 1 hour. The reaction mixture was then poured over crushed ice and neutralized with 10% HCl (aq). The resulting solid was washed with water and dried overnight under vacuum to afford 101 (58.3 g, 96%), mp 165° C.; HPLC: YMC Pack Pro C18, 40:30:30 [KH2PO4 (0.01M, pH 3.2): CH3OH:CH3CN], 264 nm, Rt 24.3 min, 97.8% purity); MS (ESI): m/z 305 (M+H, 100), 283 (26.3), 271 (26.9), 269 (75.2), 139 (16.2).
