실험 절차

4-Chloro-6-(4-nitro-phenoxy)-pyrimidine (1 g, 3.97 mmol), p-anisidine (514 mg, 4.178 mmol), and diisopropylethylamine (0.715 mL, 4.178 mmol) dissolved in 2-propanol (27 mL) are stirred under reflux under Ar. After 16 h, p-anisidine (245 mg, 1.99 mmol) is added and the reaction mixture is stirred for additional 20 h. After cooling the reaction mixture down to rt, compound of Stage 47.2 precipitates as white crystals: M+H=339.1; 1H-NMR (400 MHz, DMSO-d6): 9.49 (s, 1H, NH-pyrimidinyl), 8.25 (s, 1H, pyrimidine), 8.23/7.40/6.90 (d/d/d/, 9.0 Hz, 2H/4H/2H, phenyl-oxolphenyl-OMe), 6.18 (s, 1H, pyrimidinyl), 3.72 (s, 3H, CH3—O); Rf (MeOH/CH2Cl2=1:9): 0.44; HPLC (System 1): 6.15 min.
