Reaction Steps

The title compound was prepared as described in Example 381, using methyl 3-{1-perhydro-2H-pyran-2-yl-5-[1-(triphenylmethyl)(1,2,4-triazol-3-yl)]-1H-indazol-3-yl}benzoate (0.401 g, 0.62 mmol) and lithium hydroxide (0.046 g, 1.92 mmol) in tetrahydrofuran (3 mL) and water (2 mL); 1-hydroxybenzotriazole (0.252 g, 1.86 mmol), cyclohexylamine (0.213 mL, 1.86 mmol), 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride (0.357 g, 1.86 mmol), and additional tetrahydrofuran (2 mL); 4 N hydrochloride solution in dioxane (10 mL). The final crude product was purified by preparative HPLC (10–90% acetonitrile to H2O, 20 min.) (0.015 g, 6% yield over 3 steps): 1H NMR (CD3OD) δ 8.79 (s, 1H), 8.43 (t, 1H), 8.40 (br s, 1H), 8.19 (dt, 1H), 8.12 (d, 1H), 7.88 (dt, 1H), 7.70 (d, 1H), 7.65 (t, 1H), 3.92 (br s, 1H), 2.01 (m, 2H), 1.83 (m, 2H), 1.71 (d, 1H), 1.43 (m, 4H), 1.25 (m, 1H); ES-MS (m/z) 387 [M+1]+.
