To a stirred solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine (synthesis described for example A18) (81 mg, 0.31 mmol, 1.0 eq.) in MeCN (7 mL) was added TEA (0.17 mL, 1.2 mmol, 4.0 eq.) followed by phenyl 3-fluoro-4-(2-methoxyethoxy)phenylcarbamate (95 mg, 0.31 mmol, 1.0 eq.) at RT and stirred at reflux for 16 h. The solvent was evaporated under vacuum. The crude product obtained was purified by column chromatography (eluent EtOAc/n-hexane 1:1) to yield example A17 (121 mg; 83%).
