Reaktionsschritte

To a solution of of N-(4-fluorophenyl)-6-mercaptonicotinamide (0.024 g, 0.097 mmol, see Example 1) in 2 mL of DMF was added cesium carbonate (0.094 g, 0.29 mmol) and propyl bromoacetate (0.025 μL). The mixture was stirred for 30 minutes and poured into ethyl acetate and water. The organic layer was removed, dried over sodium sulfate, filtered, and the solvents removed in vacuo. Purification by trituration using ethyl acetate/hexanes gave 34 mg (76%) of the titled product as a white solid: 1H NMR (300 MHz, DMSO-d6) δ 10.36 (s 1H), 8.88 (m, 1H), 8.12 (m, 1H), 7.73 (m, 2H), 7.49 (m, 1H), 7.18 (m, 2H), 4.09 (s, 2H), 4.02 (m, 2H), 1.54 (m, 2H), 0.82 (m, 3H); MS (EI) m/z 347.06 (M−H)−.
