摘要：
The preparation of two radioiodinated analogs of the epidermal growth factor receptor tyrosine kinase (EGFrTK) inhibitor PD153035 (4-(3'-bromoanilino)-6,7-dimethoxyquinazoline) are reported herein. The two analogs, 4-(3'-[125I]iodoanilino)-6,7-dimethoxyquinazoline and 4-(3'-[125I]iodoanilino)-6,7-diethoxyquinazoline, were synthesized via iododestannylation of the corresponding 4-(3'-trimethylstannylanilino)-6,7-dialkoxyquinazolines to form the desired I-125 labeled products in good yield, high radiochemical purity (>99%) and high specific activity.
