EXAMPLE 12 Synthesis of 2-methyl-6-trifluoromethylindole In a stainless steel autoclave having an internal volume of 100 mL, 1.26 g (5.1 mmol) of 2-nitro4-trifluoromethylphenylacetone, 72 mg (4 mol %) of cyclopentadienyldicarbonyliron (dimer) and 40 g of toluene were placed under nitrogen atmosphere. After the atmosphere inside of the reactor was substituted by nitrogen gas (10 kgf/cm2) three times, carbon monoxide gas was injected (30 kgf/cm2), and the resulting mixture was reacted at a temperature of 120 C. for 5 hours. After cooling, the reaction solution was subjected to quantitative analysis with liquid chromatography. As a result of it, it was confirmed that 5-fluoro-2-nitrophenylacetone was completely disappeared and 0.87 g (yield 86.0%) of 2-methyl-6-trifluoromethylindole was formed.
