実験手順

3-{4-[2-(4-Aminophenyl)ethoxy]phenyl}-(S)-2-ethoxypropanoic acid hydro chloride (described in Example 56a) (0.2 g; 0.547 mmole) was dissolved in tetrahydrofurane (5 ml). Sodium hydrogencarbonate (0.053 g; 0.631 mmole) was added and the mixture was stirred for a little while. 4-tert-Butylbenzoyl chloride (0.118 g; 0.6 mmole) was added. The reaction mixture was stirred overnight and then evaporated to dryness. Dichloromethane and water were added to the residue and the phases were separated. The organic phase was dried with magnesium sulfate and the solvent was evaporated. Chromatography of the residue on silica gel(Isolute, SI) using dichloromethane:heptane (1:1), then dichloromethane and finally methanol: dichloromethane (1:99) as eluants gave 0.238 g (89% yield) of 3-{4-[2-{4-(4-[tert-butyl]benzoyl)aminophenyl}ethoxy]phenyl}-2-(S)-ethoxypropanoic acid.
