Reaction Steps

The title compound (80 mg, 99%) as a white solid was prepared from 5-(2-chlorophenyl)-4-(4-chlorophenyl)-2-hydrazinylpyridine (50 mg, 0.15 mmol) and 2-(2-methyl-6-(trifluoromethyl)pyridin-3-yl)acetic acid (49.3 mg, 0.225 mmol) in a manner analogous to that in which N′-(6-(2-chlorophenyl)-5-(4-chlorophenyl)pyridazin-3-yl)-2-(4-(trifluoromethyl)phenyl)acetohydrazide (Example 11A) was prepared. HPLC/MS: retention time=3.63 min, [M+H]+=531.1.
