Versuchsvorschrift

To 3.6 g of methyl 3-(3-tert-butyloxycarbonylaminomethylphenyl)propionate (C3) in 36 ml of tetrahydrofurane 14.8 ml of 1N aqueous sodium hydroxide solution are added and the mixture is stirred at RT for 2 days. After neutralization with 14.8 ml 1N hydrochloric acid solution and dilution with water the mixture is extracted three times with ethyl acetate. The combined extracts are dried over magnesium sulfate, filtered and the solvent removed in vacuo to give 3.5 g of the title compound as a brownish oil which solidifies on standing in a refrigerator. The mass spectrum shows the molecular peak MNH4+ at 297 Da.
