Reaction Steps

The title compound (17 mg, 68%) as a light yellow powder was prepared from 6-bromo-7-(4-chlorophenyl)-5-methyl-2-((6-(trifluoromethyl)pyridin-3-yl)methyl)-[1,2,4]triazolo[4,3-a]pyridin-3(2H)-one (25 mg, 0.05 mmol) and phenylboronic acid (25 mg, 0.2 mmol) by procedures analogous to those used for the preparation of 4-(2-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-3-oxo-8-phenyl-2,3-dihydro-[1,2,4]triazolo[4,3-a]pyridin-7-yl)benzonitrile. HPLC/MS: retention time=4.14 min, [M+H]+=495.3.
