To a stirred solution of phenyl 4-(3-hydroxyoxetan-3-yl)phenylcarbamate (100 mg, 0.35 mmol, 1.0 eq) and (1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (119.3 mg, 0.35 mmol, 1.0 eq) in DCM (10 mL) was added TEA (106 mg, 1.049 mmol, 3.0 eq) at RT and stirred at 40° C. overnight. The mixture was diluted with DCM (30 mL) and washed with water (10 mL), brine (10 mL) and dried over anhydrous Na2SO4 and concentrated. Crude product was purified by CC using MeOH/CHCl3 (1:9) to get 1-((1-(3-chlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(4-(3-hydroxyoxetan-3-yl)phenyl)urea (100 mg; 61%) as a white solid (TLC system: MeOH/CHCl3 (1:9); Rf: 0.45).
