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 (0.431 g, 0.667 mmol) in a tetrahydrofuran/water mixture (2.70 mL/1.62 mL) was added lithium hydroxide monohydrate (0.0840 g, 2.00 mmol) and the mixture heated at 60° C. for 21 h. To this mixture was added tetrahydrofuran (2.16 mL), 2,2-dimethylpropyl amine (0.174 g, 2.00 mmol), 1-hydroxybenzotriazole hydrate (0.270 g, 2.00 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.384 g, 2.00 mmol). This reaction mixture was stirred for 67 h at ambient temperature. The mixture was extracted with ethyl acetate (2×). The combined organic extracts were washed with an aqueous saturated sodium bicarbonate solution, washed with brine, dried over anhydrous sodium sulfate, filtered and evaporated. Purification of the residue by flash chromatography with 40–60% ethyl acetate/hexanes gave the title compound (0.337 g, 72% yield). ES-MS (m/z) 459 [M+1(−Tr)]+
