Procedure

To a stirred solution of (1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (0.206 mg, 0.66 mmol, 1.0 eq) in DCM (5 mL) was added TEA (0.13 g, 1.32 mmol, 2.0 eq) followed by phenyl 3-fluoro-4-(3-hydroxyoxetan-3-yl)phenylcarbamate (0.2 g, 0.66 mmol, 1.0 eq) at RT and stirred for 16 h. The reaction mixture was extracted with DCM (20 mL), washed with water (15 mL), brine (15 mL), dried over anhydrous Na2SO4 and evaporated under vacuum. Crude product was purified by CC using EtOAc/PE (7:3) to get 1-((1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(3-hydroxyoxetan-3-yl)phenyl)urea (0.075 g; 23%) as off white solid (TLC system: EtOAc/PE (1:1); Rf: 0.55).
