Reaction Steps

A mixture of 3-fluoro-4-nitro-phenol (4.94 g, 31.4 mmol), triisopropylsilyl chloride (6.40 mL, 29.9 mmol), and imidazole (4.85 g, 70.7 mmol) in 70 mL of dichloromethane is stirred for 1.5 hours. Dichloromethane (100 mL) is added and the mixture is washed with water and brine, dried (MgSO4), and concentrated under reduced pressure. The residue is purified on silica gel (120 g) eluting with a gradient of ethyl acetate in heptane (0 to 80%) to provide the title compound (8.55 g, 87%) as an oil. ES/MS m/e 314.3.0 (M+1).
