The synthesis of the fibrinogen receptor antagonist [ 3 H]L-767,679 and its ethyl ester prodrug [ 3 H]L-767,685 is described. Bromination of an appropriate benzolaclam followed by catalytic tritiation with tritium gas gave a labelled benzolactam that was converted to [ 3 H]L-767,685 via a coupling/deprotection sequence. Hydrolysis of [ 3 H]L-767,685 then gave the acid [ 3 H]L-767,679. These two compounds
描述了纤维蛋白原受体拮抗剂 [ 3 H] L-767,679 及其乙酯前药 [ 3 H] L-767,685 的合成。适当的苯并内酰胺溴化,然后用氚气催化氚化,得到标记的苯内酰胺,通过偶联/脱保护序列将其转化为[ 3 H]L-767,685。[ 3 H]L-767,685的水解然后得到酸[ 3 H]L-767,679。这两种化合物的比活性为10-16 Ci/mmol。
