실험 절차

(The following reaction is done in an anhydrous N2 atmosphere.) Suspend EDCHCl (175 mg, 0.91 mmol) and Et3N (127 μL, 0.91 mmol) in anhydrous DCM (8.0 mL) and stir the resulting solution for 5 min at rt. Add 3-(3,4,5-Trimethoxy-phenyl)-propionic acid (219 mg, 0.91 mmol) and DMAP (22 mg, 0.18 mmol) and stir the resulting solution for 10 min. Add cis-4-Amino-cyclohexanecarboxylic acid methyl ester (74) (136 mg, 0.87 mmol) and stir the reaction solution 2d at rt Remove solvent and purify the crude product by flash chromatography (silica gel, EtOAc/CyH 3+1, later EtOAc) to obtain cis-{4-[3-(3,4,5-Trimethoxy-phenyl)-propionylamino]-cyclohexanecarboxylic acid methyl ester (75) (254 mg, 76%) as a colorless viscous oil. 1H NMR (400 MHz, CDCl3): 1.40-1.51 (m, 2 H); 1.59-1.70 (m, 4H); 1.70-1.82 (m, 2H); 2.40-2.48 (m, 3H); 2.88 (t, 2H, J=7.6 Hz); 3.65 (s, 3H); 3.79 (s, 3H); 3.82 (s, 6H); 3.86-3.95 (m, 1H); 5.33 (br.d, 1H, J=7.3 Hz); 6.40 (s, 2H).
