A solution of 120 mg of 4-(4-aminomethylphenyl)-1-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3-hydroxypropyl]azetidin-2-one (17), and 48 μl of diisopropylethylamine in 1 ml of dimethylformamide was added to a solution of 40 mg of sulfoacetic acid, 110 μl of diisopropylcarbodiimide, and 76 mg of hydroxybenzotriazole in 2 ml of dimethylformamide, and the mixture was stirred at room temperature for 12 h. The reaction solution was concentrated and separated by HPLC (Knauer Eurospher-100-10-C18, water (0.1% trifluoroacetic acid)/acetonitrile (0.1% trifluoroacetic acid)=80/20->10/90). This gave the product of molecular weight 544.58 (C27H26F2N2O6S1); MS (ESI) 527.10 (M+H+—H2O)
