Reaction Steps

Preparation according to Example 3: 3-(1-ethyl-1,2,3,6-tetrahydropyridin-4-yl)-2-fluoro-N,N-dimethylbenzenesulfonamide (0.27 g, 0.86 mmol), methanol (10 ml), platinum oxide (0.05 g). Yield: 0.16 g (59%). The amine was converted to fumaric acid salt and recrystallized from ethanol/diisopropyl ether: M.p. 151-152° C. MS m/z (relative intensity, 70 eV) 314 (M+, 18), 313 (11), 300 (17), 299 (bp) 191 (11).
