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, 0.621 mmol) and lithium hydroxide (0.048 g, 2.00 mmol) in tetrahydrofuran (2.5 mL) and water (1.5 mL); 1-hydroxybenzotriazole (0.252 g, 1.86 mmol), 1,2,3,4-tetrahydro-1-naphthylamine (0.288 mL, 1.96 mmol), 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride (0.360 g, 1.88 mmol), and additional tetrahydrofuran (2.5 mL); 4 N hydrochloride solution in dioxane (10 mL). The final crude product was purified by preparative HPLC (30–80% acetonitrile in H2O, 20 min.) (0.035 g, 13% yield over 3 steps): 1H NMR (CD3OD) δ 8.82 (s, 1H), 8.59 (s, 1H), 8.37 (br s, 1H), 8.26 (dt, 1H), 8.12 (d, 1H), 8.04 (d, 1H), 7.72 (t, 2H), 7.24 (d, 1H), 7.15 (t, 1H), 7.05 (d, 1H), 2.81 (m, 4H), 1.81 (m, 4H); ES-MS (m/z) 435 [M+1]+.
