Procedure

Following the procedure of Example 1, 2,2'-pyridil (603 mg, 2.84 mmol) and 5-methyl-2-guanidinobenzimidazole (489 mg, 2.58 mmol) in methanol (17 mL) was treated with a solution of sodium hydroxide (113.6 mg, 2.84 mmol) in 2.8 mL of water. The title compound was isolated as a grey powder (450 mg, 63% yield). mp: 290-291 ° C. (dec); 1H NMR (300 MHz, d6 -DMSO) δ 11.3 br s, NH, 2 H), 10.0 (br s, NH, 2 H), 8.5 (br s, NH, 2 H), 8.32 (d, J=4.2 Hz, 2 H), 7.54 (t, J=7.6 Hz, 2 H), 7.31 (d, J=7.6 Hz, 2 H), 7.16 (d, J=7.8 Hz, 2 H), 7.16-7.09 (m, 2 H), 7.09 (s, 2 H), 7.14 br s, 2 H), 6.86 (d, J=7.8, Hz, 2 H), 2.34 (s, 6 H); MS (ESI) m/z 555 [M+H]+.
