Reaction Steps

[5-(3-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(4-morpholin-4-yl-phenyl)-amine was prepared from 5-(3-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (137 mg, 0.475 mmol) and 4-(4-bromo-phenyl)-morpholine (138 mg, 0.57 mmol) in a manner analogous to Example 77 to yield [5-(3-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(4-morpholin-4-yl-phenyl)-amine (53.8 mg, 24%) as a yellow powder following purification on a 40 g Isco silica gel column using 0-5% methanol in dichloromethane as an eluent.
