Versuchsvorschrift
The product is prepared analogously to intermediate product 1b starting from 1-(2-amino-phenyl)-cyclohexanol and tert-butyl (1,1-dimethyl-3-oxo-propyl)-carbamate. After column chromatography (silica gel, hexane/EtOAc 7:1) the product is obtained as a colourless oil. Yield: 2.65 g (66%); Rf=0.50 (silica gel, hexane/EtOAc 4:1).
