Ortho Lithiation of <i>N</i>-Pivaloylfluoroanilines as a Useful Tool for Either Selective Methylation or Benzoxazole Synthesis
Lithiation of N-pivaloyl-3,4-difluoroaniline (1a) with a slight excess of 2 mole equiv of n-butyllithium followed by methylation was studied. The reaction was found to be useful for either the selective methylation of 3,4-difluoroaniline or the synthesis of benzoxazole derivatives, depending on the reaction temperature. In the reaction of N-pivaloyl-3-chloro-4-fluoroaniline (1b) and N-pivaloyl-3-fluoroaniline (1c), the reaction proceeded rather sluggishly but benzoxazole formation predominated.

cyclization of 5 in the presence of polyphosphoric acid (PPA) as a catalyst, gave the indole esters 2 and 3 which could be separated by repeated chromatography columns (Scheme 1) . However, since compound 2 was obtained as minor isomer by this procedure? we investigated a more convenientsynthesis. We could not find literature describing the synthesis of 4,5-dihalodisubstituted indole-2-carboxylate as
