Procedure

To a stirred solution of methyl 3-{1-perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)]-1H-indazol-3-yl}benzoate (0.400 g, 0.619 mmol) in a tetrahydrofuran/water mixture (2.50 mL/1.00 mL) was added lithium hydroxide monohydrate (0.0780 g, 1.86 mmol) and the mixture heated at 60° C. for 21 h. To this mixture was added tetrahydrofuran (2.00 mL), tert-butylamine (0.195 mL, 1.86 mmol), 1-hydroxybenzotriazole hydrate (0.251 g, 1.86 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.356 g, 1.86 mmol). This mixture was stirred for 18 h at ambient temperature. After the mixture was extracted with ethyl acetate (2×), the combined organic extracts were washed with aqueous saturated sodium bicarbonate, followed by brine, dried over anhydrous sodium sulfate, filtered and evaporated. Purification of the residue by flash chromatography with 40–100% ethyl acetate/hexanes gave the title compound (0.334 g, 78% yield). ES-MS (m/z) 445 [M+1(−Tr)]+
