Imidazole → Tert-butyldimethyl(3-(thiophen-2-yl)propoxy)silane

Participants

Reaction Steps

To a solution of 3-(thiophene-2-yl)propanol (500 mg, 3.52 mmol) and imidazole (288 mg, 4.22 mmol) in 9 mL anhydrous dichloromethane was added TBS-Cl (584 mg, 3.87 mmol). The resulting mixture was stirred at room temperature for 30 minutes and poured into 50 mL water. Organics were extracted with ether (2×40 mL), dried over magnesium sulfate, filtered and concentrated. The crude oil was subjected to chromatography on silica gel with gradient elution (1-2% ethyl acetate in hexanes) to give tert-butyldimethyl(3-(thiophen-2-yl)propoxy)silane (787 mg, 87%). Used without further characterization.
