実験手順
To 2.5 g of (2S,4S)-2-Hydroxymethyl-4-phenyl-pyrrolidine-1-carboxylic acid tert-butyl ester (9.01 mmol) in 70 ml dichloromethane were added 1.92 g of triethylamine (18.02 mmol) and 1.03 g of methanesulfonylchloride (9.01 mmol), dissolved in 5 ml dichloromethane. The reaction was stirred for 16 h at room temperature and yielded 3.4 g of product after standard workup.
