Procedure

Prepared according to Procedure C using Intermediate 2d (100 mg, 0.294 mmol), adenine (44 mg, 0.323 mmol), K2CO3 (45 mg, 0.323 mmol), and DMF (1 mL). The crude product was recrystallized from EtOH to provide 50 mg of a yellow solid (39%), mp 294.5-294.8° C. (decomposes). 1H NMR (DMSO-d6) δ: 8.10 (d, J=2.2 Hz, 1H); 8.05 (s, 1H); 8.03 (s, 1H); 7.86 (dd, J=2.4, 8.8 Hz, 1H); 7.75-7.82 (m, 2H); 7.59-7.67 (m, 2H); 7.53 (d, J=8.7 Hz, 1H); 7.22 (br s, 2H); 5.13 (d, J=17 Hz, 1H); 4.95 (d, J=17 Hz, 1H). 13C NMR (DMSO-d6) ppm: 159.7, 156.2, 152.9, 151.9, 150.1, 145.5, 141.8, 135.7, 133.1, 132.3, 132.2, 131.9, 131.1, 130.9, 130.0, 129.4, 125.9, 122.0, 118.4, 44.9. MS (ES): m/z 438.0 (M+). Anal. calcd. for C20H13Cl2N7O: C, 54.81; H, 2.99; N, 22.37. Found: C, 54.72; H, 2.87; N, 22.18.
