[0252] Dissolve [4-hexyl-2-(4-methylphenyl)thiazol-5-yl]methanol (500 mg, 1.727 mmol) in anhydrous dichloromethane (6 ml), add molecular sieves (3A powder, 890 mg) and Corey reagent (crorochrome) piridium) (745mg, 3.455mmol). After stirring at room temperature for 30 minutes, diethyl ether (20 mL) and silica gel (Wako-gel, C-300HG, 2 g) were added and stirred at room temperature for further 10 minutes. The reaction mixture was filtered through a glass filter, and the residue was washed with diethyl ether to obtain a filtrate, from which the solvent was distilled off under reduced pressure. The resulting residue was subjected to silica gel column chromatography to obtain the title compound (346 mg, yield 70%) as white crystals from the hexane:ethyl acetate (8:1, v / v) fraction.

Description

technical field [0001] The present invention relates to an activator of peroxisome proliferator-activated receptor (PPAR). Background technique [0002] It is known that there are three subtypes of peroxisome proliferator-activated receptors (PPARs), which are called PPARα, PPARγ, and PPARδ. (Proc. Natl. Acad. Sci. USA, 91, p7335-7359, 1994: hereinafter referred to as Non-Patent Document 1.) [0003] Furthermore, various compounds have so far reported transcriptional activation actions of each subtype of PPAR, hypoglycemic and lipid metabolism-improving actions, and the like. For example, GW-590735 (GSK), KRP-101 (キョ-リン) and NS-220 (Roche-Japan Shinyaku) have been reported as selective α agonists having lipid metabolism improving effects. (J Pharmacol Exp Ther 309(3): 970, Jun 2001: hereinafter referred to as Non-Patent Document 2) [0004] In addition, a variety of drugs showing dual agonist (dualagonist) activity of PPARγ and PPARα are known, and KRP-297 (Kyorin) repres...
