Procedure

(trans-4-Amino-cyclohexyl)-acetic acid ethyl ester hydrochloride (10.0 g, 45 mmol, intermediate B) was dissolved in CH2Cl2 (150 ml) and Et3N and AcCl (3.89 g, 50 mmol) were added. The reaction mixture was stirred 3 h at room temperature before washing it with H2O and brine. After drying (Na2SO4) the solvent was evaporated to yield 8.42 g (82%, 37 mmol) of a white solid. MS (m/z): 228.3 ([M+H]+).
