実験手順

A 25 ml round-bottom flask with a magnetic stirrer was charged with 6-chloro-7-fluoro-8-nitro-9H-β-carboline (102 mg, 0.38 mmol) in 5 ml of anhydrous DMF. To the resulting orange mixture at RT was slowly added sodium thioethoxide (80% pure, 69.7 mg, 0.66 mmol) in powder form. The reaction mixture was stirred at RT for 45 minutes, then added drop-wise to a 5:1 mixture of H2O/saturated sodium bicarbonate (˜30 ml). The resulting precipitated solid was collected by suction filtration, washed with 1:1 hexanes/diethyl ether (2×20 ml), and air-dried to afford 95.0 mg of 6-chloro-7-ethylsulfanyl-8-nitro-9H-β-carboline as an orange solid (79%).
