Versuchsvorschrift

A mixture of 1-(3-chloro-benzyl)-7-(2-chloro-ethoxy)-5-fluoro-3-(naphthalene-1-sulfonyl)-1H-indazole (0.075 g, 0.14 mmoles) and methylamine (0.56 mmoles) in DMSO (1 mL) was stirred under nitrogen at 100° C. for 4 hours. Mixture was cooled to room temperature, diluted with water, extracted with EtOAc, washed with water (2×), brine (1×), dried over Na2SO4, and concentrated under vacuum. Compound was purified by flash chromatography using as eluent 5% CH3OH/EtOAc. The purified compound was dissolved in methanol, 1M HCl in ether (0.1 mL, 0.1 mmoles) was added, and compound was dried to afford the title compound as the HCl salt.
