実験手順
8.1 A suspension of 540 mg ((R)-3-amino-pyrrolidin-1-yl)-acetic acid ethyl ester dihydrochloride (example 1.2) in 5 ml THF was treated with 1.2 ml TEA and 530 mg 5-chlorothiophene-2-sulfonylchloride. The reaction mixture was stirred over night at r.t., then taken up in EtOAc and washed with water and brine. The organic layer was dried over MgSO4, filtered and concentrated to give 690 mg [(R)-3-(5-chloro-thiophene-2-sulfonylamino)-pyrrolidin-1-yl]-acetic acid ethyl ester. Oil. 353.1 ([M+H]+)
