Reaction Steps

N-[3-(2-Amino-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-phenyl]-N-methyl-methanesulfonamide was prepared from 8-bromo-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (500.0 mg, 2.347 mmol) and N-methyl-N-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-methanesulfonamide (800.0 mg, 2.571 mmol) in a manner analogous to Example 2c.
