Non-peptide fibrinogen receptor antagonists. 4. The synthesis of [3H]L-756,568

The synthesis of [3H]L-756,568, an orally active fibrinogen receptor antagonist, is described. Two synthetic pathways were developed using either bromoindoles 2a/2b or bromoaryl sulfonamide 11 as the precursor. Use of the bromoaryl sulfonamide
