Procedure: To a mixed liquid of 2.00 g of (1RS,2SR)-2-[(tert-butoxycarbonyl)amino]cyclohexanecarboxylic acid and 40 ml of dichloromethane were added 1.41 ml of 2-(trimethylsilyl)ethanol, 0.40 g of DMAP, and 2.21 g of WSC in this order, followed by stirring at room temperature for 60 hours. After evaporating the solvent, ethyl acetate was added thereto, followed by washing with water, a 5% aqueous citric acid solution, a saturated aqueous sodium hydrogen carbonate solution, and a saturated aqueous sodium chloride solution in this order. The organic layer was dried over anhydrous magnesium sulfate and the solvent was then evaporated to obtain 2.82 g of 2-(trimethylsilyl)ethyl(1RS,2SR)-2-[(tert-butoxycarbonyl)amino]cyclohexanecarboxylate as a colorless oily substance. After evaporating the solvent, ethyl acetate was added by washing with water The organic layer was dried over anhydrous magnesium sulfate the solvent was then evaporated
