Procedure

Prepared according to Procedure C using 2l (250 mg, 0.746 mmol), adenine (111 mg, 0.821 mmol), K2CO3 (113 mg, 0.821 mmol), and DMF (4 mL). The crude product was chromatographed in MeOH/CH2Cl2 and recrystallized from EtOH to provide 124 mg of a brown solid (38%), mp 257.0-257.1° C. 1H NMR (DMSO-d6) δ: 8.06 (s, 1H); 8.01 (s, 1H); 7.71 (t, J=8.0 Hz, 1H); 7.57 (dd, J=0.9, 7.9 Hz, 1H); 7.52-7.59 (m, 1H); 7.50 (dd, J=1.6, 7.8 Hz, 1H); 7.38 (dd, J=1.1, 8.2 Hz, 1H); 7.27 (dd, J=0.6, 8.3 Hz, 1H); 7.24 (br s, 2H); 7.17 (dt, J=0.9, 7.6 Hz, 1H); 5.07 (d, J=17 Hz, 1H); 4.97 (d, J=17 Hz, 1H); 3.79 (s, 3H). 13C NMR (DMSO-d6) ppm: 158.8, 156.2, 154.7, 153.2, 152.8, 150.1, 149.3, 142.0, 135.1, 133.2, 131.8, 130.1, 130.1, 127.2, 123.8, 121.6, 118.4, 117.9, 113.1, 56.2, 44.8.
