Reaction Steps

A solution of (2R)-1-[(4-tert-butoxy-2-fluorophenyl)sulfonyl]-4-[4-fluoro-2-(trifluoromethyl)phenyl]-2-methylpiperazine (375 mg, 0.76 mmol) in DCM (25 mL) was added TFA (5 mL). The reaction was allowed to stir for 1 hour, after which it was judged complete by LCMS. The reaction was concentrated in vacuo to remove excess TFA, and the crude oil was dissolved in DCM (20 mL) and washed with saturated NaHCO3(aq) (3×25 mL). The organic phase was dried over Na2SO4, and decanted, then concentrated in vacuo affording the desired phenol in >95% purity, which was used in subsequent synthetic steps without purification. HRMS: calcd for C18H17F5N2O3S+H+, 437.09528. found ([M+H]+), 437.09527.
