2-Ethyl-1-butanol → Toluene-4-sulfonic acid 2-ethylbutyl ester

Participants

Reaction Steps

To a solution of 2-ethyl-1-butanol (1.00 g, 9.79 mmol), triethylenediamine (1.32 g, 11.7 mmol) in DCM (30 mL, 0.5 mol) cooled to 0° C. was added p-toluenesulfonyl chloride (1.96 g, 10.3 mmol) in DCM (10 mL) The reaction mixture was stirred for 30 min, and extracted with 1.0N NaOH (2×40 mL). The organic layer was collected, dried over anhydrous sodium sulfate, filtered, and isolated by rotary evaporation to give the title compound (2.40 g).
