Procedure

The obtained methyl 3-[4-[3-[4-hexyl-2-(4-methylphenyl)thiazol-5-yl]propenoyl]-2-methylphenyl]acrylate (112 mg, 0.230 mmol) was dissolved in methanol (1 mL) and tetrahydrofuran (1 mL). 10% palladium carbon (22 mg) was added to the solution to cause replacement of hydrogen in the system. The mixture was stirred at room temperature for 3 hours. The reaction mixture was filtrated with Celite. The filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography with hexane/ethyl acetate (5:1, v/v) to give the desired compound (46 mg) as colorless oil (yield 41%).
