Product 1

HCID 729493763-(2-(2-Methyl-5-(6-((4-methylpiperazin-1-yl)methyl)-1H-benzo[d]imidazol-2-yl)phenyl)ethynyl)imidazo[1,2-b]pyridazine

Procedure

The title compound was synthesized from 3-ethynylimidazo[1,2-b]pyridazine and 2-(3-iodo-4-methylphenyl)-6-((4-methylpiperazin-1-yl)methyl)-1 H-benzo[d]imidazole (as prepared in Example 1) in a manner similar to that described for in Example 1. The intermediate compound 3-ethynylimidazo[1,2-b]pyridazin was made as for Example 1 (Step 1 to 3) with the spectra below: 1H NMR (300 MHz, DMSO-d6) δ: 8.63-8.64 (1 H, m), 8.18-8.21 (1 H, m), 8.10 (1 H, s), 7.32-7.35 (1 H, m), 4.94 (1 H, s).
