실험 절차

In an argon atmosphere, to a stirred solution of 2-chloro-4-[[(3-hydroxyphenyl)amino]carbonyl]benzoic acid (45 mg; 0.1472 mmol), 4-(2,6-dichlorobenzoylamino)-L-phenylalanine methyl ester (60 mg; 0.1488 mmol) and HBTU (59 mg; 0.16 mmol) in dimethylformamide (3 mL) was added DIPEA (0.102 mL; 0.585 mmol). The reaction mixture was stirred for 17 hr at room temperature, then was concentrated to dryness in vacuo and the residue was partitioned between dichloromethane (25 mL) and 0.5 N HCl (10 mL). The organic layer was washed with water and the aqueous layers were backwashed in turn with dichloromethane. The combined dichloromethane extracts were dried (Na2SO4) and evaporated to give 80 mg of crude material that was crystallized from methanol-ethyl acetate to provide 38 mg of N-[[2-chloro-4-[[(3-hydroxyphenyl)amino]carbonyl]phenyl]carbonyl]-4-[[(2,6-dichlorophenyl)carbonyl]amino]-L-phenylalanine methyl ester. mp 230-232° C. FAB HRMS: (C32H26Cl3N3O6) Obs. Mass 654.0952 Calcd. Mass 654.0965 (M+H).
