Reaktionsschritte

A2 was prepared following the general procedure reported for A1 using 2,4-dichloro-1,3,5-triazine and 3-aminobenzenesulfonamide as reacting agents. The crude product was purified by flash chromatography on silica gel (cHex/EtOAc=20:1 to 1:20) to yield the desired product A2 as a white solid (35%). 1H NMR (400 MHz, d6-DMSO, 300K) δ 7.41 (s, 2H), 7.59 (m, 2H), 7.85 (d, J=6.9 Hz, 1H), 8.21 (br.s, 1H), 8.69 (s, 1H), 11.02 (s, 1H). MS (ES) C9H8ClN5O2S requires: 285. found: 286 (M+H)+.
