Product 1

HCID 729504174-Chloro-3-(2-(imidazo[1,2-b]pyridazin-3-yl)ethynyl)-N-(4-(4-methyl-1H-imidazol-1-yl)-3-(trifluoromethyl)phenyl)benzamide

Procedure

The title compound was synthesized from 3-ethynylimidazo[1,2-b]pyridazine and 4-chloro-3-iodo-N-(4-(4-methyl-1H-imidazol-1-yl)-3-(trifluoromethyl)phenyl)benzamide in a manner similar to that described for in Example 1. The title compound was obtained as a light yellow solid. Mp: 153-155° C.; 1H NMR (300 MHz, CDCl3) δ: 9.39 (1H, s), 8.49 (1H, d, J=3.3 Hz), 8.08-8.18 (4H, m), 7.91-7.94 (2H, m), 7.57-7.60 (2H, m), 7.34 (1H, brs), 7.14-7.16 (1H, m), 6.85 (1H, brs), 2.28 (3H, s). HRMS (ESI-TOF+): m/z [M+H]+ calcd for C26H17ClF3N6O: 521.1099. found: 521.1092.
