Reaction Steps

To a stirred solution of (3-{1-perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)](1H-indazol-3-yl)}phenyl)-N-benzylcarboxamide (0.232 g, 0.322 mmol) was added dioxane (10.0 mL) and aqueous 6 N hydrochloric acid (10.0 mL) and the mixture heated at 50° C. for 24 h. The mixture was cooled and aqueous 6 N sodium hydroxide (20 mL). Neutralization of the aqueous layer to pH=7 with aqueous 6 N hydrochloric acid followed by extraction with ethyl acetate, drying of the organic extracts over anhydrous sodium sulfate, filtration and evaporation gave crude product. Purification by preparative HPLC (15–80% acetonitrile/water) followed by washing with saturated sodium bicarbonate and extraction with ethyl acetate gave the title compound (0.0230 g, 18% yield). 1H NMR (CD3OD) δ 8.78 (s, 1H), 8.49 (t, 1H), 8.21 (dt, 1H), 8.11 (br d, 1H), 7.93 (dt, 1H), 7.69 (t, 1H), 7.65 (d, 1H), 7.40 (dd, 2H), 7.32 (m, 2H), 7.24 (m, 1H), 4.64 (s, 2H). ES-MS (m/z) 395 [M+1]+
