실험 절차

To a stirred solution of (1-(3-chloro-2-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methanamine hydrochloride (100 mg, 0.38 mmol, 1.0 eq) in DCM (5 mL) was added TEA (0.16 mL, 1.14 mmol, 3.0 eq) followed by phenyl 3-fluoro-4-(hydroxymethyl)phenyl-carbamate (131 mg, 0.38 mmol, 1.0 eq) at RT and stirred for 16 h. The reaction mixture was diluted with water (15 mL), extracted with DCM (2×15 mL). The combined organic layer was washed with brine (15 mL), dried over anhydrous Na2SO4 and evaporated under vacuum. Crude product was purified by CC to get 1-((1-(3-chloro-2-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazol-5-yl)methyl)-3-(3-fluoro-4-(hydroxymethyl)phenyl)urea (110 mg; 61%) as off white solid (TLC system: MeOH/CHCl3 (1:9); Rf: 0.55).
