Phenyl (S)—N′-cyano-N-(7-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)carbamimidate and phenyl (R)—N′-cyano-N-(7-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)carbamimidate were treated with 3-hydrazino-6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazine in a similar manner as described above in Synthetic Example 2 to yield 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-(S)-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine and 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-(R)-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine. For example, a suspension of a single enantiomer of phenyl N′-cyano-N-(7-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulen-2-yl)carbamimidate (0.06 g, 0.16 mmol) and 3-hydrazino-6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazine (0.036 g, 0.16 mmol) in 1 mL of IPA was stirred at 90° C. for 18 h. After cooling to ambient temperature, the solvent was evaporated and the residue was purified by HPLC to provide enantiomerically pure 1-(6,7-dihydro-5H-benzo[6,7]cyclohepta[1,2-c]pyridazin-3-yl)-N3-(7-(R)-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulene-2-yl)-1H-1,2,4-triazole-3,5-diamine as a yellow solid (0.04 g, 50%). 1H NMR (DMSO-d6, 300 MHz) 9.11 (s, 1H), 7.94 (s, 1H), 7.85 (br s, 2H), 7.72 (m, 1H), 7.46 (m, 3H), 7.37 (m, 2H), 7.06 (m, 1H), 3.46 (m, 4H), 3.12 (m, 2H), 2.72 (m, 4H), 2.61 (m, 3H), 2.25 (m, 5H), 2.09-1.82 (m, 5H) ppm; MS (ES) 507 (M+H).
