Reaction Steps

The 3(S)-hydroxymethylpyrrolidine (0.9 g, 8.90 mmol), triethylamine (1.80 g, 17.8 mmol, 2.0 equiv) in 1,4-dioxane (30 mL) and water (10 mL) is stirred at room temperature and then 4-methoxyphenylsulfonyl chloride (2.02 g, 9.80 mmol, 1.10 equiv) is added. The resulting solution is stirred at room temperature for 3 h. and then the solution is acidified to pH~1 with 1 N HCl. The solution is poured into water and then extracted with CH2Cl2. The organic extracts are dried (Na2SO4) and concentrated to an oil. The oil is purified by chromatography using 1/1 hexane/EtOAc as the eluent to afford the desired product as a colorless oil.
