Reaction Steps

[5-(3-Methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-(4-morpholin-4-ylmethyl-phenyl)-amine was prepared from 5-(3-methanesulfonyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (125 mg, 0.43 mmol) and 4-(4-bromobenzyl)morpholine (122 mg, 0.48 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-ylmethyl-phenyl)-amine (118 mg, 59%) as an off-white powder following purification on a 4 g Isco silica gel column using methanol in dichloromethane (0-20%) as eluent.
