Procedure
The (S)-3-(4,5-diamino-2,3-dimethylphenyl)-4-(4-propoxyphenyl)oxazolidin-2-one was dissolved in triethyl orthoformate and was refluxed for 30 minutes. After cooling the excess of triethyl orthoformate was removed under reduced pressure. The final product was purified via FPLC using a chloroform-methanol gradient (0→10%).
