Reaktionsschritte
2-methyl-7-azaindole was prepared in two steps. First, 2-amino-3-picoline was reacted with acetyl chloride in toluene in the presence of pyridine to produce 2-acetamido-3-picoline in 65% yield. Second, pyrolysis of 2-acetamido-3-picoline in N-methylaniline in the presence of NaH at 280° C. was performed to produce 2-methyl-7-azaindole (FIG. 18) in 23% yield. This compound was characterized by NMR spectroscopy.
