preparation example Construction
[0165] In the preparation method of the compound represented by Formula 1 of the present invention, step 1) is to prepare the compound represented by Formula 4 by causing a coupling reaction between the compound represented by Formula 2 and the compound represented by Formula 3. More specifically, the compound represented by Formula 2, the compound represented by Formula 3, and triphenylphosphine were all mixed to obtain a mixed solution. Azocarboxylate reagent (Azocarboxylate reagent) is slowly added to the mixed solution at a temperature of -5°C to 10°C, followed by causing Mitsunobureaction to obtain the compound represented by Formula 4.
[0167] The reaction solvent here may be selected from the group consisting of tetrahydrofuran (THF), dic...

[0254] Production Example 1: Preparation of ethyl 3-(4-hydroxyphenyl)hex-4-ynoate
[0255]
[0256] 3-(4-Hydroxyphenyl)-hex-4-ynoic acid (20.0 g) and ethanol (200 mL) were charged into a 250 mL flask under a nitrogenatmosphere, followed by stirring to dissolve them. Sulfuric acid (9.6 mL) was slowly added to this at room temperature. The mixture was stirred at reflux for at least 6 hours. Upon completion of the reaction, distilled water (150 mL) was slowly added thereto, followed by extraction with ethyl acetate (200 mL). The extracted organic layer was dried under reduced pressure to obtain the target compound (19.5 g, 85.7%).
[0258] Production Example 2: Preparation of (S)-3-(4-hydroxyphenyl)hex-4-ynoic acid ethyl ester
[0259]
[0260] (S)-3-(4-Hydroxyphenyl)-hex-4-ynoic acid (20.0 g) and ethanol (200 mL) were charged into a 250 mL flask under a nitrogenatmosphere, followed by stirring to dissolve them. Sulfuric acid (9.6 mL) was slowly added to this at room temperature. The mixture was stirred at reflux for at least 6 hours. Upon completion of the reaction, distilled water (150 mL) was slowly added thereto, followed by extraction with ethyl acetate (200 mL). The extracted organic layer was dried under reduced pressure to obtain the target compound (21.2 g, 93.2%).

Abstract
The present invention relates to a novel 3-(4-(benzyloxy)phenyl)hex-4-inoic acid derivative, a method of preparing same and a pharmaceutical composition for preventing and treating metabolic disease including same as an effective ingredient. The novel 3-(4-(benzyloxy)phenyl)hex-4-inoic acid derivative, an optical isomer thereof, or a pharmaceutically acceptable salt thereof, according to the present invention, has an excellent effect on activation of GPR40 protein and thus has excellent promoting effect of insulinsecretion; is nontoxic when co-administrated with other drugs and is possibly co-administrated with other drugs; and has excellent effective effect of activating GPR40 proteinin vivo. Therefore, a composition including the novel 3-(4-(benzyloxy)phenyl)hex-4-inoic acid derivative, the optical isomer thereof, or the pharmaceutically acceptable salt thereof may be availably used in a pharmaceutical composition for preventing and treating metabolic disease such as obesity, type I diabetes, type II diabetes, incompatible glucose tolerance, insulin tolerance, hyperglycemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, dyslipidemia, syndrome X, etc.
Description
technical field [0001] The present invention relates to a novel 3-(4-(benzyloxy)phenyl)hex-4-ynoic acid derivative, a preparation method thereof, and a drug for preventing and treating metabolic diseases comprising the same as an active ingredient combination. Background technique [0002] Diabetes is a serious disease that continues to threaten our health, and at least 100 million people worldwide already suffer from diabetes. Diabetes can be classified into two clinical symptom categories, Type I diabetes and Type II diabetes. Type 1 diabetes, known as insulin-dependent diabetes mellitus (IDDM), results from autoimmune destruction of insulin-producing pancreatic beta cells, so that it requires regular administration of exogenous insulin. Type 2 diabetes, known as non-insulin-dependent diabetes mellitus (NIDDM), results from defective control of blood sugar. Thus, those with type II diabetes characteristically show a defect in insulin secretion or insulin resistance, whi...
