Participants

Reaction Steps

A solution of 2.05 g of 4-benzylamino-piperidine-1-carboxylic acid tert.-butyl ester and 3.39 g of sulfamide in 100 ml of 1,2-dimethoxy-ethane is refluxed for ca. 10 hours. From the mixture obtained solvent is evaporated, the evaporation residue obtained is treated with EtAc and unsoluble parts are filtered off. The filtrate obtained is subjected to chromatography on silica gel. 4-[N-(Aminosulfonyl)-benzylamino]-piperidine-1-carboxylic acid tert.butylester is obtained. mp 140-142°. 1H-NMR (DMSO) δ: 7.30-7.41 (s/m, 9+2H), 1.64 (m, 2H), 2.53-2.72 (broad, 2H), 3.71 (tt, 1H), 8.83-8.96 (broad, 2H), 4.26 (s, 2H, CH2), 6.86 (bs, 2H, NH), 7.19 (t, 1H), 7.28 (t, 1H), 7.36 (d, 1H). 13C-NMR (DMSO) δ:28.51, 30.13, 43.35, 47.11, 56.52, 79.12, 127.06, 127.48, 128.49, 140.59, 154.156.
