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 (0.595 g, 0.92 mmol) and lithium hydroxide (0.069 g, 2.87 mmol) in tetrahydrofuran (3 mL) and water (2 mL); 1-hydroxybenzotriazole (0.373 g, 2.76 mmol), 4-(2-aminoethyl)morpholine (0.362 mL, 2.76 mmol), 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride (0.535 g, 2.79 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 in H2O, 20 min.) (0.030 g, 8% yield over 3 steps): 1H NMR (CD3OD) δ 8.82 (t, 1H), 8.47 (t, 1H), 8.29 (s, 1H), 8.22 (dt, 1H), 8.14 (dd, 1H), 7.92 (dt, 1H), 7.67 (t, 2H), 3.70 (t, 4H), 3.62 (t, 2H), 2.67 (t, 2H), 2.58 (t, 4H); ES-MS (m/z) 418 [M+1]+.
