Participants

Reaction Steps

To a solution of 2-propanol (2.4 mL, 32 mmol) in dichloromethane (50 were added triethylamine (3.5 ml, 25 mmol) and ethanesulfonyl chloride (2.0 mL, 21 mmol), and the mixture was stirred at room temperature for 3 hours. The reaction mixture was washed successively with 1N hydrochloric acid, saturated aqueous sodium hydrogen carbonate and saturated brine, and dried over sodium sulfate. The drying agent was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (2.4 g, 16 mmol, 75%).
