الإجراء التجريبي

To 1.72 g (4.58 mmol) trans-Methanesulfonic acid 4-[(4-chloro-phenoxycarbonyl)-methyl-amino]-cyclohexylmethyl ester in 17 ml DMF, 0.78 g (6.86 mmol, 1.5 eq) potassium thioacetate were added and the mixture was heated to 100° C. for 10 min. The mixture was concentrated under vacuum and the residue was dissolved in saturated NaHCO3/Et2O(3×). The organic phases were washed with brine, dried over Na2SO4 and evaporated to yield 1.69 g (quantitative) of trans-Thioacetic acid S-{4-[(4-chloro-phenoxycarbonyl)-methyl-amino]-cyclohexylmethyl} ester, MS: 356 (MH+).
