Vorschrift

N-[5-[(3,5-Dimethoxyphenyl)methoxy]-2H-pyrazol-3-yl]-4-[(3R,5S)-3,4,5-trimethylpiperazin-1-yl]benzamide was prepared following the procedure for Example 100, but starting from ethyl 4-((3R,5S)-3,4,5-trimethylpiperazin-1-yl)benzoate (0.276 g, 1.00 mmol) and 5-[(3,5-dimethoxyphenyl)methoxy]-2H-pyrazol-3-amine (0.249 g, 1 mmol) and a 2M solution of trimethylaluminium in toluene (1.25 mL, 2.5 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 (0.027 g, 5.63%) as a white solid.
