TBAF (1M in THF, 9.10 mL, 9.10 mmol) was added to a sol. of N-[3-(tert-butyl-dimethyl-silanyloxymethyl)-4-chloro-benzyl]-3,3,3-trifluoro-propionamide (1.80 g, 4.55 mmol) in THF (45 mL) at 0° C. The mixture was stirred for 1 h while warming up to rt. EtOAc (100 mL) was added, and the mixture was washed with aq. sat. NH4Cl (3×) and water (4×). The org. layer was dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the crude by FC (EtOAc/heptane 70:30) yielded the title compound (835 mg, 65%). LC-MS: tR=0.76 min; ES+: 323.02.
