Versuchsvorschrift

To a stirred solution of (1-(3-ethoxy-5-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (100 mg, 0.300 mmol, 1.0 eq) in acetonitrile (7 mL) was added TEA (0.166 mL, 1.20 mmol, 4.0 eq) followed by phenyl 3-fluoro-4-((2-hydroxyethoxy)methyl)-phenylcarbamate (93 mg, 0.306 mmol, 1.02 eq) and stirred at reflux for 16 h. The solvent of the reaction mixture was evaporated and the residue was purified by column chromatography (EtOAc/cyclohexane (1:1)) to get 1-((1-(3-ethoxy-5-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-((2-hydroxyethoxy)methyl)phenyl)urea (60 mg, 39%).
