Procedure

Prepared according to Procedure C using Intermediate 2k (210 mg, 0.650 mmol), adenine (97 mg, 0.715 mmol), K2CO3 (99 mg, 0.715 mmol), and DMF (4 mL). The crude product was recrystallized from EtOH to provide 137 mg of a tan solid (50%), mp 295.6-295.8° C. (decomposes). 1H NMR (DMSO-d6) δ: 8.05 (s, 1H); 8.04 (s, 1H); 7.75 (t, J=7.6 Hz, 1H); 7.74 (t, J=7.9 Hz, 1H); 7.62-7.69 (m, 1H); 7.61 (d, J=7.6 Hz, 1H); 7.47-7.55 (m, 1H); 7.48 (d, J=7.8 Hz, 1H); 7.41 (d, J=8.0 Hz, 1H); 7.24 (br s, 2H); 5.19 (d, J=17 Hz, 1H); 5.03 (d, J=17 Hz, 1H). 13C NMR (DMSO-d6) ppm: 158.7, 157.6 (d, J=250 Hz), 156.2, 152.8, 152.4, 150.0, 149.2, 141.8, 135.4, 133.3, 132.5 (d, J=8.0 Hz), 131.0, 130.4, 127.3, 126.2 (d, J=3.5 Hz), 123.1 (d, J=14 Hz), 118.4, 117.6, 117.2 (d, J=19 Hz), 45.1. MS (ES): m/z 422.0 (M+). Anal. calcd. for C20H13ClFN7O.0.05C2H6O: C, 56.92; H, 3.16; Cl, 8.36; N, 23.12. Found: C, 56.79; H, 3.20; Cl, 8.46; N, 22.79.
