Reaction Steps

0.66 g (2.3 mmol) of trans-methyl-{2-[4-(2-oxo-ethyl)-cyclohexyl]-ethyl}-carbamic acid tert-butyl ester were dissolved in 2 mL of CCl4, 2 mL of acetonitrile and 3 mL of water. To this mixture were added 2.4 mg (0.012 mmol, 0.01 eq) of anhydrous ruthenium (III) chloride, followed by 2.04 g (9.5 mmol, 4.1 eq) of sodium metaperiodate in small portions. Stirring was continued at RT for 2 h, the mixture was filtered and partitioned between CH2Cl2 and water. The organic phase was washed with water and dried over magnesium sulfate. Column chromatography of the crude product with a gradient of n-heptane: EtOAc 1:4 to 1:1 gave 430 mg (62%) of trans-{4-[2-(tert-butoxycarbonyl-methyl-amino)-ethyl]-cyclohexyl}-acetic acid as colorless oil, MS: 317 (M+NH4+).
