Reaction Steps

(S)-2-Benzoylamino-4-dibenzofuran-2-yl-4-oxo-butyric acid methyl ester, prepared as described in Step (b) of Example 6, was dissolved in tetrahydrofuran containing one equivalent of triethylamine. The solution was stirred at room temperature for 1 hour, and then the solvent was removed by evaporation to give a solid. The solid was washed with water to give methyl (S)-2-amino-4-dibenzofuran-2-yl-4-oxo-butyrate as a mono-hydrate.
