実験手順
To a solution of trans-2-carboxymethoxy-cyclohexyl ammonium chloride (1.048 g, 5 mmoles) in 1N NaOH (15 ml), there was aded a solution of p-toluenesulphonyl chloride (1.048 g, 5.5 mmoles) in diethyl ether (20 ml). The mixture was vigorously stirred for 20 hours at room temperature. The aqueous phase was separated, washed with diethyl ether (20 ml), acidified with HCl 18% to pH 2 and extracted with diethyl ether (5×20 ml). The organic extracts were dried with MgSO4, the drying agent was filtered off and filtrate was evaporated in vacuo. The residue was recrystallized from diisopropyl ether. Thus, there were obtained 1.09 g (67%) of the title compound in the form of white crystals, melting point 56°-58° C.
