Procedure

Prepared according to Procedure C using Intermediate 2g (250 mg, 0.783 mmol), adenine (116 mg, 0.862 mmol), K2CO3 (119 mg, 0.862 mmol), and DMF (4 mL). The crude product was recrystallized from EtOH to provide 93 mg of a pale yellow solid (28%), mp 190.7-190.9° C. 1H NMR (DMSO-d6) δ: 8.05 (s, 1H); 8.03 (s, 1H); 7.76-7.79 (m, 1H); 7.71-7.74 (m, 1H); 7.59-7.67 (m, 1H); 7.34 (d, J=7.4 Hz, 1H); 7.28 (d, J=8.2 Hz, 1H); 7.24 (br s, 2H); 5.07 (d, J=17 Hz, 1H); 4.92 (d, J=17 Hz, 1H); 2.73 (s, 3H). 13C NMR (DMSO-d6) ppm: 161.1, 156.2, 152.8, 150.9, 150.1, 148.3, 141.9, 141.0, 134.6, 133.6, 132.2, 131.9, 131.3, 130.8, 130.3, 129.3, 125.9, 119.1, 118.4, 44.8, 22.8. MS (ES): m/z 418.1 (M+). Anal. calcd. for C21H16ClN7O.H2O: C, 57.87; H, 4.16; Cl, 8.13; N, 22.49. Found: C, 57.78; H, 3.99; Cl, 8.38; N, 22.32.
