Reaction Steps

TBAF (1M in THF, 8.84 mL, 8.84 mmol) was added to a sol. of [3-(tert-butyl-dimethyl-silanyloxymethyl)-4-chloro-benzyl]-(2-fluoro-ethyl)-carbamic acid tert-butyl ester (1.91 g, 4.42 mmol) in THF (44.2 mL) at 0° C. The mixture was stirred for 1 h while warming up to rt. EtOAc (100 mL) was added, and the resulting mixture was washed with aq. sat. NH4Cl (2×) and brine (1×). The org. layer was dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the crude by FC (EtOAc/heptane 30:70) yielded the title compound (901 mg, 64%). LC-MS: tR=0.64 min; ES+: 318.07.
