Versuchsvorschrift
4-[N-(2,3-Epoxypropyl)sulphamoyl]nitrobenzene (Method 116, 1 g, 3.88 mmol) and piperidine (0.34 g, 4 mmol) in 1-propanol (75 ml) were heated at reflux for 20 hours. The mixture was cooled and the solvent evaporated. The resulting yellow oil was triturated with diethyl ether collected by filtration and dried under vacuum to give the title compound 1.2 g (90%). NMR: 1.26-1.50 (m, 6H), 2.10-2.28 (m, 6H), 2.70 (dd, 1H), 2.90 (dd, 1H), 3.55 (m, 1H), 8.04 (d, 2H), 8.40 (d, 2H); m/z: 344.
