Versuchsvorschrift

To the suspension of 3-{5-amino-4-[3-(2-bromoethoxy)-benzoyl]-pyrazol-1-yl}-N-cyclopropyl-4-methyl-benzamide (24 mg, 0.05 mmol) in EtOH (1 ml) was added 1-methylpiperazine (100 mg, 1 mmol) and the mixture was stirred at 80° C. overnight. The solvent was removed, residue was dissolved in EtOAc, washed by water, dried over Na2SO4. Solvent was removed, desired product was obtained as a colorless oil (18 mg, 72%). HPLC (4 minute gradient) tR 1.33 min; MS m/z 503.29 [M+H]+.
