A 500 mL round bottom flask was charged with tert-butyldimethylchlorosilane (73.9 g, 491 mmol) (available from Aldrich), DMF (220 mL), 2-fluorophenol (41.3 mL, 446 mmol) (available from Aldrich), and imidazole (75.9 g, 1115 mmol). The pale yellow solution was stirred for 1.5 hours at 25° C. and diluted with hexanes (1 L). The organic phase was washed with water (1×300 mL), saturated aqueous NaHCO3 (3×300 mL), water (3×300 mL) and brine (1×300 mL). The organic phase was then dried (MgSO4), and concentrated to afford 84.A (101 g, 100% yield) as a colorless liquid. The crude product was used without further purification.
