実験手順

0.213 g (0.341 mmol) of 2-(2-Benzoyl-phenylamino)-3-{4-[2-(5-methyl-2-phenyl-oxazol-4-yl)-ethoxy]-naphthalen-1-yl}-propionic acid ethyl ester was dissolved in 1.6 ml of THF/EtOH=1/1 and treated with 0.568 ml of 3N NaOH(5 eq). The reaction flask was stirred for 20 h at ambient temperature. The mixture was then poured onto crashed ice/NH4Cl, extracted twice with AcOEt, washed with brine, dried over sodium sulfate, and evaporated to dryness. Twofold crystallization from hexane/AcOEt yielded 0.199 g of the title product as yellow crystals of mp. 125° (dec.).
