Reaction Steps

A solution of N-[4-(2-Methyl-2,3,4,9-tetrahydro-1H-β-carbolin-6-ylsulfamoyl)-phenyl]-acetamide (example 7) (80 mg, 0.2 mmol) in 1 mL of an aqueous 10% de NaOH solution was refluxed for 2 h. The resulting mixture was treated with H2O (25 mL) and EtOAc (25 mL) and neutralized by addition of AcOH glacial. The aqueous phase was washed again with EtOAc and the combined organic extracts dried to afford 50 mg of 4-amino-N-(2-methyl-2,3,4,9-tetrahydro-1H-β-carbolin-6-yl)-benzenesulfonamide as a cream colored amorphous solid, mp 236-237° C. 1H-NMR (300 MHz, DMSO-d6): (ppm) 2.36 (s, 3H); 2.55 (bb, 2H); 2.61 (bb, 2H); 3.45 (bb, 2H); 5.83 (bb, 2H); 6.44 (sys AB, 2H, J=8.7 Hz); 6.68 (dd, 1H, J=8.4, 1.8 Hz); 6.99 (bb, 1H); 7.05 (d, 1H, J=8.4 Hz); 7.25 (sys AB, 2H, J=8.7 Hz); 9.27 (s, 1H); 10.63 (s, 1H).
