実験手順

To a mixture of 4-({cyclohexyl[2-ethyl-5-(tetrahydro-2H-thiopyran-4-yl)thiophen-3-yl]methyl}amino)benzoic acid (1.00 g) synthesized above, ethyl β-alaninate hydrochloride (415 mg), 1-hydroxybenzotriazole monohydrate (414 mg) and triethylamine (376 μL) in N,N-dimethylformamide (20 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (518 mg), and the mixture was stirred at room temperature overnight. 1N Hydrochloric acid was added to quench the reaction, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (50% ethyl acetate/hexane) to give the title compound (1.06 g, 87%) as a white solid.
