98 mg of 1,1-dimethylethyl 2-[[4-[2-[(carboxymethyl)(2-furanylmethyl)amino]-ethyl]phenyl]thio]-2-methyl-propanoate, 33 mg of hydroxybenzotriazole, 0.09 ml of triethylamine, 34 mg of 2,5-dimethyl-4-methoxyaniline and 49 mg of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride are dissolved in 5 ml of dichloromethane. The mixture is stirred at room temperature for 20 h and extracted with 1 N NaOH, 1 N HCl, water and sat. NaCl solution. The combined organic phases are dried (MgSO4) and purified chromatographically (dichloromethane/ethyl acetate 5+1). This gives 48 mg of a viscous oil.
