Procedure
To a solution of 2-(4-(5-(4-chlorophenyl)-4,4,5-trifluoro-4,5-dihydrothiazol-2-yl)phenoxy)acetic acid (45.7 mg, 114 μmol) in DMF (5.7 mL) were added the coupling agents HOBt (18.4 mg, 136 μmol) and EDC.HCl (26.1 mg, 0.136 mmol). Then, butylamine was added (13.6 μL, 136 μmol) and the mixture was stirred for 2 h at room temperature. When the reaction was completed, it was diluted with dicloromethane (20 mL) and washed with H2O (3×5 mL). The organic extracts were dried over Na2SO4, filtered and evaporated under reduced pressure. The residue was absorbed onto silica then subjected to flash chromatography (SiO2, hexane:AcOEt, 6:4), obtaining 18.1 mg of N-butyl-2-(4-(5-(4-chlorophenyl)-4,4,5-trifluoro-4,5-dihydrothiazol-2-yl)phenoxy)acetamide (35% yield).
