Dazoxiben is an orally active thromboxane synthase inhibitor.[1] It has shown a significant clinical improvement in patients with Raynaud's syndrome.[2]

Synthesis

Dazoxiben synthesis:[3][4][5][6]

One convenient synthesis starts with the O-chloroethyl ether of p-hydroxybenzamide and proceeds bydisplacement with imidazole to give 2. Hydrolysis of the amide function completes the synthesis of dazoxiben.
