実験手順

To a stirred solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine (synthesis described for example A141) (102 mg, 0.387 mmol, 1.0 eq) in MeCN (9 mL) was added TEA (0.214 mL, 1.55 mmol, 4.0 eq) followed by phenyl 3-fluoro-4-(2-hydroxyethyl)phenylcarbamate (108 mg, 0.395 mmol, 1.02 eq) and the mixture was stirred for 16 h at reflux. The reaction mixture was concentrated under vacuum and the residue purified by CC using EtOAc/hexane (2:1) as eluent to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(2-hydroxyethyl)phenyl)urea (159 mg; 92%, white solid).
