실험 절차

1-(2-Chloro-benzenesulfonyl)-4-(2-methoxy-ethyl)-piperidine-4-carboxylic acid (2.82 g) were dissolved in THF (30 ml) under an argon atmosphere at RT and then sequentially treated with O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (3.26 g), (4-amino-phenyl)-acetic acid ethyl ester (1.536 g) and N-methyl morpholine (1.04 ml). The reaction mixture was stirred 12 h at RT, and 1 h at reflux to complete the reaction. The mixture was partitioned between AcOEt and 1N HCl/water, the layers were separated; the organic layer was dried over sodium sulphate and then removed in vacuo. The residue was purified by chromatography on silica gel (CH2Cl2/AcOEt, 19/1 to 9/1) to give the desired (4-{[1-(2-chloro-benzenesulfonyl)-4-(2-methoxy-ethyl)-piperidine-4-carbonyl]-amino}-phenyl)-acetic acid ethyl ester (2.47 g) which was directly used in the next step.
