Reaction Steps

This was prepared in 21% yield using a similar procedure to that described in Example 18 except using pyridine-4-boronic acid instead of 3-trifluoromethylbenzeneboronic acid and 3-bromo-2-(2-ethyl-2H-[1,2,4]triazol-3-ylmethoxy)-7-(2-fluorophenyl)pyrazolo[1,5-d][1,2,4]triazine instead of 3-bromo-7-(2-fluorophenyl)-2-(2-methyl-2H-[1,2,4]triazol-3-ylmethoxy)pyrazolo[1,5-d][1,2,4]triazine.
