Example 5: Synthesis of 6-fluoro-2-methylindole In a 100 mL stainless steel autoclave, 1.0 g (5.1 mmol) of 1-(4-fluoro-2-nitrophenyl)propan-2-one, 130 mg (4 mol%) of triruthenium tricarbonyl, 397 mg of 2,2'-bipyridine and 40 g of toluene were added and the system was reacted under nitrogen protection under the same conditions as in Example 4. After completion of the reaction, the reaction solution was quantitatively analyzed by high performance liquid chromatography (HPLC). The analytical results showed 100% conversion of 1-(4-fluoro-2-nitrophenyl)propan-2-one and gave 0.65 g (97.0% yield) of 6-fluoro-2-methylindole.
