Reaction Steps

2-Hydrazinyl-5,6,7,8,9,10-hexahydrocycloocta[d]pyrimidine (58 mg, 0.30 mmol) and (Z)-phenyl N′-cyano-N-(3-fluoro-4-(4-methyl-1,4-diazepan-1-yl)phenyl)carbamimidate (111 mg, 0.30 mmol) were dissolved in anhydrous N-methylpyrrolidone (0.5 mL) and subjected to microwave irradiation (220° C., 10 min). The crude reaction mixture was directly purified by C-18 reversed phase chromatography, eluting with acetonitrile and water containing 0.05% formic acid to give N3-(3-fluoro-4-(4-methyl-1,4-diazepan-1-yl)phenyl)-1-(5,6,7,8,9,10-hexahydrocycloocta[d]pyrimidin-2-yl)-1H-1,2,4-triazole-3,5-diamine, compound #4, as a beige solid, 30 mg; 1H NMR (CDCl3/MeOD4, 300 MHz) 8.22 (s, 1H), 8.19 (s, 1H), 7.26 (d, 1H), 6.93 (d, 1H), 6.71 (t, 1H), 3.23 (m, 6H), 3.16 (m, 2H), 2.81 (m, 2H), 2.69 (s, 3H), 2.61 (m, 2H), 2.12 (m, 2H), 1.69 (m, 2H), 1.56 (m, 2H), 1.27 (m, 4H) ppm; MS (ES) 466.27 (M+H).
