Versuchsvorschrift

To a solution of (+/−)-3-amino-1N-BOC-pyrrolidine (0.5 g) in MeCN (10 mL) was added triethylamine (0.41 mL) then methanesulfonyl chloride (0.22 mL). The mixture was stirred for 2.5 h. An aqueous work-up followed by purification on silica gave 3-methanesulfonylamino-pyrrolidine-1-carboxylic acid tert-butyl ester (0.49 g).
