실험 절차

Methylisothiocyanate (43 μL) was added to a solution of N-(4-amino-2-chlorobenzoyl)-4-(2-methoxyphenyl)-L-phenylalanine methyl ester (55.1 mg) in anhydrous DMF (1 mL) containing DIEA (22 μL) and DMAP (catalitic amount). The resulting mixture was then heated at 90° C. under N2 for 1 d. After cooling, the mixture was diluted with EtOAc, washed sequentially with 1N HCl, satd. NaHCO3 and water, dried (MgSO4) and evaporated. The residue was purified by preparative TLC (silica gel) using CH2Cl2/MeOH (15:1) as an eluent to give N-[2-chloro-4-(3-methylthioureido)benzoyl]-4-(2-methoxyphenyl)-L-phenylalanine methyl ester (22.7 mg). ESMS: m/z 512 (MH+).
