실험 절차

Compound (11) is prepared from compound (2) in an analogous manner as compound (3) described in Example I, B. Thus, 5-amino-3-methylcarbamoyl-2,4,6-triiodobenzoyl chloride (2) reacted with 2,3-diacetoxypropionyl chloride in DMAc provides 5-(2,3-diacetoxypropionylamino)-3-methylcarbamoyl-2,4,6-triiodobenzoyl chloride (11) in approximately 90% yield.
