Procedure

[N-(3-{1-Perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)](1H-indazol-3-yl)}phenyl)-2-pyridylcarboxamide was dissolved in 4 mL of 4.0 N HCl in 1,4-dioxane and the reaction was stirred at room temperature overnight. After neutralization with aqueous NaHCO3, the crude product was extracted with ethyl acetate and purified by preparative HPLC. (0.037 g, 39% yield over 2 steps): 1H NMR (CD3OD) δ 8.81 (s, 1H), 8.76 (dt, 1H), 8.55 (t, 1H), 8.45 (br s, 1H), 8.25 (dt, 1H), 8.12 (dd, 1H), 8.09 (td, 1H), 8.00 (dt, 1H), 7.85 (dt, 2H), 7.73 (d, 1H), 7.65 (ddd, 1H), 7.59 (t, 1H); ES-MS (m/z) 382 [M+H]+.
