Procedure

To a stirred solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine hydrochloride (synthesis described for example A106) (0.104 mg, 0.348 mmol, 1.0 eq) in MeCN (8 mL) was added TEA (0.193 mL, 1.39 mmol, 4.0 eq) followed by addition of phenyl 3-fluoro-4-(1-hydroxycyclopropyl)phenylcarbamate (0.10 mg, 0.355 mmol, 1.02 eq) at RT and the mixture was stirred at reflux overnight. The solvents were evaporated and the crude product was purified by CC (eluent EtOAc/cyclohexane 1:2) to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(1-hydroxycyclopropyl)phenyl)urea (104 mg; 65%).
