The reaction mixture was diluted with water (10 mL) and extracted into DCM (25 mL). The organic layer was washed with brine (10 mL), dried over (Na2SO4) and the solvent evaporated under vacuum. The resulting residue was purified by CC using EtOAc/PE (1:1) as eluent to get 1-((1-(2,3-dichlorophenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(hydroxymethyl)phenyl)urea (70 mg; 23%) as white solid (TLC system: EtOAc, Rf: 0.55).
