Procedure

4-(4-Cyclobutylpiperazin-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 5-[(3,5-dimethoxyphenyl)methoxy]-2H-pyrazol-3-amine (0.173 g, 0.69 mmol), ethyl 4-(4-cyclobutylpiperazin-1-yl)benzoate (0.2 g, 0.69 mmol) and a 2M solution of trimethylaluminium in toluene (1.387 mL, 2.77 mmol) in toluene (10 ml) at room temperature for 20 h. The reaction mixture was poured into acetone (20 mL), quenched with excess damp sodium sulphite, filtered and evaporated to afford a yellow solid. Acetonitrile (10 ml) was added and this was filtered to afford the title compound (0.079 g, 23.17%) as a white solid.
