Versuchsvorschrift
To a solution of 2-[(1-benzothien-2-ylcarbonyl)amino]nicotinamide (0.3 g, 1.0 mmol) in ethanol (20 mL) was added NaOH (10 N, 0.3 mL, 3.0 mmol). The resulting solution was heated to reflux overnight. On cooling to rt the solvent was removed under reduced pressure. The residue was dissolved in excess of water and acidified with HCl. The resulting precipitate was filtered and washed with water to afford the product as yellow powder (0.16 g, 57%). HPLC/MS: (M+H)+ 280.0 m/z; Retention time (LC-MS)=2.66 min; 1H NMR (DMSO-D6): 13.17 (1H, s); 8.94(1H, m); 8.61(1H, s); 8.50(1H, d); 8.08(1H, d); 7.97(1H, d); 7.52(3H, m).
