Procedure

Prepared according to Procedure C using Intermediate 2i (400 mg, 1.05 mmol), adenine (155 mg, 1.15 mmol), K2CO3 (159 mg, 1.15 mmol), and DMF (5 mL). The crude product was recrystallized from EtOH to provide 344 mg of a white solid (68%), mp 299.9-300.1° C. (discolors). 1H NMR (DMSO-d6) δ: 8.08 (s, 1H); 7.89 (s, 1H); 7.58-7.73 (m, 5H); 7.51 (d, J=7.9 Hz, 1H); 7.46 (d, J=7.5 Hz, 2H); 7.27-7.41 (m, 3H); 7.14-7.27 (m, 3H); 5.14 (d, J=17 Hz, 1H); 4.82 (d, J=17 Hz, 1H). 13C NMR (DMSO-d6) ppm: 159.6, 156.2, 152.8, 152.5, 150.0, 149.0, 141.7, 140.2, 137.7, 135.0, 133.3, 133.2, 131.8, 130.7, 130.1, 129.8, 129.5, 128.8, 128.6, 128.4, 127.1, 118.4, 117.6, 45.3. MS (ES): m/z 480.1 (M+). Anal. calcd. for C26H18ClN7O: C, 65.07; H, 3.78; Cl, 7.39; N, 20.43. Found: C, 64.77; H, 3.75; Cl, 7.43; N, 20.35.
