Versuchsvorschrift
Bromine (160 μL, 3.12 mmol, 1.0 eq) is added at 10° C. to a stirred solution of (trans-4-acetyl-cyclohexyl)-carbamic acid benzyl ester (850 mg, 3.12 mmol, 1.0 eq) in methanol (30 mL). After 4 hours stirring at 10° C., the reaction mixture is diluted with petroleum ether (15 mL) and the resulting precipitate is collected by filtration to afford [trans-4-(2-bromo-acetyl)-cyclohexyl]-carbamic acid benzyl ester as a white solid (920 mg, 83% yield).
