Procedure

4-(4-Cyclopropylpiperazin-1-yl)-N-[5-[(3,5-dimethoxyphenyl)methoxy]-2H-pyrazol-3-yl]benzamide was prepared following the procedure as outlined for Example 100, starting from ethyl 4-(4-cyclopropylpiperazin-1-yl)benzoate (0.329 g, 1.2 mmol), 5-[(3,5-dimethoxyphenyl)methoxy]-2H-pyrazol-3-amine hydrochloride (0.343 g, 1.20 mmol) and 2M trimethylaluminium in toluene (1.500 mL, 3.00 mmol). The crude product was purified by preparative HPLC, using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford the title compound (0.022 g, 3.84%) as a white solid. 1H NMR (500.13 MHz, DMSOd6) δ 0.34-0.40 (2H, m), 0.45-0.50 (2H, m), 1.67-1.75 (1H, m), 2.67-2.73 (4H, m), 3.24-3.32 (4H, m), 3.78 (6H, s), 5.08 (2H, s), 5.68 (1H, s), 6.42-6.46 (1H, m), 6.58-6.61 (2H, m), 6.95 (2H, d), 7.83 (2H, d), 10.30 (1H, s), 11.01 (1H, s). MS: m/z 478 (MH+).
