Reaction Steps

To a stirred solution of 2-fluoro-4-[4-methyl-2-[4-(2-trimethylsilylthiazol-4-yl)phenyl]-1H-imidazol-1-yl]benzenesulfonamide (crude, 0.634 mmol) in THF (3 mL) was added tetrabutylammonium fluoride (0.95 mL, 1.0 M solution in THF, 0.95 mmol) at 0° C. The reaction mixture was warmed to room temperature and stirred for 30 minutes. The reaction mixture was added water (20 mL) and extracted with ethyl acetate (20 mL×3). The organic layer was washed with water and brine. After dried over MgSO4 and concentration in vacuo. The crude mixture was purified by flash chromatography eluting with hexane/ethyl acetate (1/3). The resulting solid was recrystallized from ethyl acetate-hexane to give the title compound (0.116 g, 44.1% yield, via 2 steps).
