Procedure

To a solution of 1.75 g (5.84 mmol) trans-[4-(5-Hydroxy pentyl)-cyclohexyl)-methyl-carbamic acid tert-butyl ester and 0.5 ml (6.42 mmol) of methanesulfonyl chloride in 20 ml CH2Cl2 was added, under cooling with an ice bath, 1.56 ml (11.7 mmol) of Et3N. The mixture was stirred for 3 h at RT. The reaction-mixture was then partitioned between ether/1N HCl and water. The ether-solution was concentrated in vacuo to yield 2.12 g (96%) of clean trans-Methansulfonic acid 5[-4-(tert-butoxy carbonyl-methyl-amino)-cyclohexyl)-pentylester.
