Procedure

To a solution of acetic acid 1-acetoxymethyl-2-[3-(2,3-diacetoxy-propylcarbamoyl)-2,4,6-triiodo-5-isocyanato-benzoylamino]-ethyl ester in dichloromethane was added 1,3-diamino-2-hydroxypropane (0.5 equivalent). The reaction mixture was stirred for 18 hours and then purified by column chromatography to give Acetic acid 2-acetoxy-3-[3-[3-(3-{3-[3,5-bis-(2,3-diacetoxy-propylcarbamoyl)-2,4,6-triiodo phenyl]-ureido}-2-hydroxy-propyl)-ureido]-5-(2,3-diacetoxy-propylcarbamoyl)-2,4,6-triiodo-benzoylamino]-propyl ester. This was dissolved in methanol and treated with aqueous ammonia. The material was purified by preparatie HPLC to give 1,3-bis-[N,N′-Bis-(2,3-dihydroxy-propyl)-2,4,6-triiodo-5-ureido-isophthalamide]-2-hydroxypropane as a white powder after freeze drying.
