実験手順

5.28 g of 3-fluoropyridin-2-ylsulfonamide and 18.03 ml of allylamine are stirred for 6 hours in a pressurised vessel at a temperature of 125° C. The reaction solution is subsequently concentrated, the crystallisate obtained is dissolved in methylene chloride and a little acetonitrile, the mixture is purified by chromatography using methylene chloride/ethyl acetate (4:1) as the eluent mixture and silica gel as the carrier material. 5.1 g of 3-allylaminopyridin-2-ylsulfonamide (intermediate No. 2.002) of a melting point of 134°-135° C. are obtained.
