Reaction Steps

The title compound (27 mg, 74%) was prepared from 8-bromo-7-(4-chlorophenyl)-5-methyl-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one (25 mg, 0.074 mmol) and 5-(chloromethyl)-2-(trifluoromethyl)pyridine (21.7 mg, 0.11 mmol) by procedures analogous to those used for the preparation of 8-bromo-7-(4-chlorophenyl)-5-methyl-2-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one. HPLC/MS: retention time=4.03 min, [M+H]+=498.1.
