There is provided a more industrially advantageous process for preparing novel pyridine derivatives expected to be used as medicines. A process for preparing 3-(6-hydroxy-1-methyl-1H-benzimidazol-2-yl)benzoic acid esters as intermediates with high quality, in short steps and in a high yield, as well as novel benzoic acid esters as their precursors and a process for preparing the same.
The present invention relates to a novel pyridine derivative or a pharmacologically acceptable ester thereof, or a pharmacologically acceptable salt of the derivative or ester, which has an excellent hypoglycemic effect or treats and/or prevents the onset of a disorder of carbohydrate or lipid metabolism or a disease mediated by peroxisome proliferator-activated receptor (PPAR) γ. A compound represented by the general formula (I):
[wherein R represents a pyridyl group substituted with 1 to 3 group(s) independently selected from Substituent Group A, and Substituent Group A represents a halogen atom, a C
1
-C
6
alkyl group and a C
1
-C
6
alkoxy group] or a pharmacologically acceptable ester thereof, or a pharmacologically acceptable salt of the compound or ester.
