Reaction Steps

To a suspension of 2-amino-7-methyl-8-(3-trifluoromethyl-phenyl)-[1,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid methyl ester (Int. 35, 1.0 g, 2.857 mmol) in THF (10 mL) and water (5 mL) was added lithium hydroxide (273 mg, 11.34 mmol) and the reaction mixture was stirred at 45° C. for 1.75 hrs. Cooled then acidified to pH 1. The resultant precipitate was collected by filtration, washing with water, to afford the title compound as a white solid (590 mg).
