Komponenten

Versuchsvorschrift

A mixture of phenyl 3-(2-phenyloxyphenyl)propionate (0.45 g, 1.30 mmol), 2N NaOH (20 ml) and MeOH (10 ml) was stirred at room temperature overnight, which was then neutralized to pH˜2 with concentrated HCl and extracted with EtOAc (100 ml). The organic phase was washed with brine and dried over sodium sulfate and concentrated in vacuo to yield 3-(2-phenyloxyphenyl)propionic acid as an oil. This was used for next step without further purification.
