실험 절차

A solution of (1R,2R)-1,2-diphenylethylenediamine (1.16 g, 4.74 mmol), picolinic acid (596 mg, 4.79 mmol, 1.01 eq.), N,N-dimethyl-4-aminopyridine (100 mg, 0.82 mmol, 0.17 eq.) and 1,3-dicyclohexycarbodiimide (1.07 g, 5.2 mmol, 1.1 eq.) in dichloromethane (40 ml) was stirred at room temperature under N2 for 18 hours. The reaction mixture was filtered and washed with water. Column chromatography on silica gel using EtOAc/CH2Cl2 (4:1) afforded 1.06 g of white solids as title compound (71% yield). NMR and GCMS confirmed the structure.
