Reaction Steps

4-({3-[2-Benzyl-7-(trifluoromethyl)-2H-indazol-3-yl]phenoxy}methyl)benzonitrile (37 mg, 1 eq) was treated with trimethylsilyl azide (21 μL, 2 eq) and di-n-butyltin oxide (5 mg, 0.3 eq) in toluene (2.5 mL) at 100° C. until full conversion. After cooling, most of the solvent was removed in vacuo and the residue was taken in methanol. Purification by flash chromatography, eluent 10% methanol in dichloromethane, afforded the title compound in 87% yleld.
