Procedure

The title compound was prepared as described in Example 76. To a solution of 3-(4-fluorophenyl)-1H-indazole-5-carboxylic acid (0.200 g, 0.781 mmol) in tetrahydrofuran (5 mL) was added 1-hydroxybenzotriazole hydrate (0.316 g, 2.34 mmol) followed by 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.449 g, 2.34 mmol), 3-amino-1-propanol (0.178 mL, 2.34 mmol) and N,N-dimethylformamide (2 mL). The solution was stirred for 16 h at room temperature. Water (40 mL) was added and the solid was filtered and dried in a vacuum oven to give the title compound (0.192 g, 78% yield): 1H NMR (DMSO-d6) δ 13.45 (s, 1H), 8.59 (t, 1H), 8.53 (s, 1H), 8.08 (AB quartet, 2H), 7.91 (dd, 1H), 7.62 (d, 1H), 7.40 (t, 2H), 4.50 (t, 1H), 3.48 (q, 2H), 3.36 (q, 2H), 1.71 (pentet, 2H); ES-MS (m/z) 314 [M+1]+.
