Procedure

A solution composed of compound 4 (0.065 g, 0.194 mmol), Hunig's base (0.17 mL, 0.97 mmol) and ethanol (6 mL) was heated at 65° C. for 30 min, then 1-(3,5-diamino-6-chloropyrazine-2-carbony)-2-methylisothiourea hydriodide (5, 0.072 g, 0.213 mmol) was added. The resulting solution was continuously stirred at 65° C. temperature for an additional three hours, then cooled to room temperature. The solvent was then removed by evaporation, and the resulting residue was column chromatographed on silica gel eluting with a mixture of methanol (0-22%), ammonium hydroxide (0-2.2%) and dichloromethane (100-75.8%). This afforded compound 6 (0.078 g, 84%) as a yellow solid. m.p. 92-94° C. (decomposed). 1H NMR (500 MHz, DMSO-d6) δ 1.54 (m, 4H), 2.51 (m, 2H), 2.89 (m, 2H), 3.20 (s, 2H), 3.31 (m, 2H), 4.00 (m, 2H), 6.89 (d, 2H), 7.08 (br, 2H), 7.12 (d, 2H), 7.57 (br, 2H), 9.08 (br, 1H). m/z (ESI) 478.
