Versuchsvorschrift
To 6.01 g (0.021 mmol) of (2-chloro-3,5-dimethoxy-phenyl)-carbamic acid tert-butyl ester was added 15 mL of trifluoroacetic acid. The reaction was stirred for 3 hours at room temperature, then concentrated in vacuo. The residue was made basic with a saturated solution of sodium bicarbonate, then extracted three times with dichloromethane. The combined dichloromethane layers were dried with magnesium sulfate and concentrated in vacuo to give 3.98 g of the title compound, which was used as is in the following example.
