Procedure

A solution of 17.1 g (63.1 mmol) of trans-[2-(4-hydroxymethyl-cyclohexyl)-ethyl]-methyl-carbamic acid tert-butyl ester in 60 mL of CCl4, 60 mL of water and 90 mL of acetonitrile were treated with 0.075 g (0.33mmol, 0.05 eq) of ruthenium (III) chloride•hydrate and 55.4 g (259 mmol, 4.1 eq) of sodium metaperiodate within 30 min. After 6 h the reaction was decanted and washed with CH2Cl2 (×3). The decanted phase was partitioned between CH2Cl2 (×3)/H2O, dried over Na2SO4 and evaporated to yield 17.24 g (96%) of trans-4-[2-(tert-butoxycarbonyl-methyl-amino)-ethyl]-cyclohexanecarboxylic acid, MS: 284 (M−H−).
