Reaction Steps

Stir a mixture of 4-[1-(3,5-bistrifluoromethylbenzyl)-5-phenyl-1H-[1,2,3]triazol-4-yl]-3-(2-chlorophenyl)-isoxazolo[4,3-c]pyridine (350 g, 0.583 mol) and 5% Pt—C (35 g) in ethyl acetate (3.5 L) under a H2 (˜5 psi) atmosphere for 20 hours. Filter through hyflo, wash with ethyl acetate (3.5 L) and concentrate to a solid. Dissolve in ethyl acetate (7 L) and add Darco® (600 g). Stir for 2 hours then filter through hyflo. Rinse filter cake with ethyl acetate (3.5 L) and concentrate filtrates to give the title compound.
