PROCEDURE

实验过程

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 1,1,1-tris(hydroxymethyl)ethane (0.3 equivalent). The reaction mixture was stirred for 18 hours and then purified by column chromatography to give acetic acid 2-acetoxy-3-[3-{2-[3,5-bis-(2,3-diacetoxy-propylcarbamoyl)-2,4,6-triiodo-phenylcarbamoyloxymethyl]-3-hydroxy-2-methyl-propoxycarbonylamino}-5-(2,3-diacetoxy-propylcarbamoyl)-2,4,6-triiodo-benzoylamino]propyl ester. This was dissolved in methanol and treated with aquesous 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-carbamido-isophthalamide]-2-methyl-2-hydroxymethylpropane as a white powder after freeze drying.
