tert-Butanol → Tert-butyl 4-(bromomethyl)benzoate

참여 물질

반응 단계

4-Bromomethylbenzoyl bromide (13.9 g, 50 mmol, 1.0 eq) was added to 50 mL of DCM, followed by t-butanol (9.6 mL, 100 mmol, 2.0 eq) and the mixture was slowly warmed to room temperature. After 20 hours, the reaction was concentrated under reduced pressure, dissolved into 350 mL EtOAc, washed with 400 mL sat. bicarbonate and 200 mL saturated aqueous NaCl. The organic was dried over MgSO4, filtered, and concentrated under reduced pressure to yield intermediate (19a) as a semisolid (7.3 g).
