Tetrahydrofuran → (6-Ethyl-5-(5-(4-isobutyl-3-methylphenyl)-1,2,4-oxadiazol-3-yl)pyridin-2-yl)methanol

Participants

Reaction Steps

The crude product of the title compound was synthesized by conducting the similar reaction to that mentioned in Example 12 (12a) using 4-isobutyl-3-methylbenzoic acid (92 mg, 0.48 mmol) that was obtained in Example 27 (27d), 1-hydroxybenzotriazole (69 mg, 0.51 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (97 mg, 0.51 mmol), 2-ethyl-N′-hydroxy-6-{[(triisopropylsilyl)oxy]methyl}pyridine-3-carboximidamide (0.16 g, 0.46 mmol) that was obtained in Example 25 (25b), and a 1.0 M solution of tetrabutylammonium fluoride in tetrahydrofuran (0.92 ml, 0.92 mmol). Subsequently, the crude product of the title compound thus obtained was purified by chromatography on a silica gel column using a mixed solvent of ethyl acetate and hexane (1:3) as the eluent to afford the title compound (0.15 g) in a yield of 93% as a white crystalline solid.
