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 (0.431 g, 0.667 mmol) in a tetrahydrofuran/water mixture (2.70 mL/0.62 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 (2.00 mL), 3-pyridylmethylamine (0.189 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 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 solution of sodium bicarbonate, followed by brine, dried over anhydrous sodium sulfate, filtered and evaporated. Purification of the residue by flash chromatography with 5% methanol/ethyl acetate gave the title compound (0.242 g, 50% yield). ES-MS (m/z) 480 [M+1(−Tr)]+
