(2-Bromoethoxy)-tert-butyldimethylsilane → HCID 67124103, compound

Participants

Reaction Steps

To a solution of example 1 (50 mg, 0.14 mmol) in DMF (8 mL), 55-65% NaH dispersion in mineral oil (6 mg, 0.15 mmol) was added. The resulting solution was stirred at room temperature for 10 min. Then (2-bromoethoxy)-tert-butyldimethylsilane (0.074 mL, 0.34 mmol) was added and the reaction was stirred at 50° C. for 14.5 h. The reaction mixture was quenched with H2O (10 mL) and extracted with EtOAc (3×10 mL). The combined organic phases were dried over anhydrous Na2SO4, filtered and concentrated. The crude product thus obtained was chromatographed over silica gel using hexanes/EtOAc mixtures of increasing polarity as eluent, to afford 55 mg of the desired compound (76% yield).
