Reaction Steps
A solution of N-(2-(4-(4-chlorophenoxy)phenylamino)-2-(3-(trifluoromethyl)phenyl)ethyl)-4-methylbenzenesulfonamide (358 mg, 0.638 mmol) and phenol (180 mg, 1.92 mmol) in 30 wt % HBr in acetic acid (3.5 mL) is heated at 80° C. for 2 h. After cooling down to room temperature, most of the solvent is removed under vacuo. The residue is then quenched with cold saturated NaHCO3 aqueous solution (40 mL) and extracted with EtOAc (3×20 mL). The combined organic layer is concentrated and purified by reverse phase HPLC to provide N1-(4-(4-chlorophenoxy)phenyl)-1-(3-(trifluoromethyl)phenyl)ethane-1,2-diamine (128 mg, 49% yield) as a light yellow oil-like product.
