Abstract :Acetal of warfarin acid has been synthesized via a hemi acetal intermediate and structurally characterized by X-ray diffraction. The crystal structure shows that the title compound was formed by the hydrolysis of warfarin acid in methanol at pH 3, with space group P21/n and unit cell parameters a = 5.859 (17), b =16.745 (5), c = 16.402 (5) Å, a = 90.00; b = 94.853 (4), and g = 90.00°.
Keywords : Warfarin acid, synthesis, acetal, crystal structure
