Procedure

A solution of 6.02 g (17.43 mmol) of trans-Methanesulfonic acid 3-[4-(tert-butoxycarbonyl-methyl-amino)-cyclohexyl]-prop-2-ynyl ester in 95 ml CH2Cl2 was treated at 0° C. with 45 ml TFA (for 20 min). After 30 min at this temperature, the reaction was evaporated and evaporated again with toluene (4 times) to give 8.17 g (quantitative) of crude trans-Methanesulfonic acid 3-(4-methylamino-cyclohexyl)-prop-2-ynyl ester.trifluoroacetate, MS: 245 (M).
