Versuchsvorschrift
0.10 g (0.39 mmol) N-(2-amino-6-chloro-4-hydroxyphenyl)tetrahydrofuran-3-carboxamide were placed in 20 mL methanol, a spatula tip of p-toluenesulphonic acid monohydrate was added and the mixture was boiled for 2 h. The reaction mixture was evaporated down i.vac. and purified by chromatography. The fractions containing product were combined and evaporated down i.vac.
