Procedure

To a stirred solution of (1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (103 mg, 0.33 mmol, 1.0 eq) in DCM (10 mL) was added TEA (0.10 mL, 0.66 mmol, 2.0 eq) followed by phenyl 3-fluoro-4-(3-hydroxyazetidin-1-yl)phenylcarbamate (100 mg, 0.33 mmol, 1.0 eq) at RT and stirred for 48 h. The reaction mixture was diluted with water (5 mL) and extracted with DCM (20 mL), washed with brine, dried over Na2SO4 and evaporated. The residue was purified by CC using 1.0% MeOH in EtOAc as eluent to obtain 1-((1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(3-hydroxyazetidin-1-yl)phenyl)urea (100 mg; 63%, light brown solid) (TLC: EtOAc/PE 3:2; Rf: 0.3).
