Abstract: Dutasteride, a new kind of antibenign prostatic hyperplasia drug, 17-β-N(2,5-bis(trifluoromethyl)) phenylcarbamoyl-4-aza-5-α-androst-1-en-3-one, was synthesized by employing amidation and DDQ/BSTFA oxidation as a pivotal step from the starting material 3-oxo-4-androstene-17-β-carboxylic acid. The total yield of dutasteride synthesi zed was 23%. The structures of the target molecule and the key intermediates were confirmed by IR,1H NMR, 13C NMR and MS. The route does not require high pressure and high temperature that may be applied to industrial production.

Key words: synthesis, dutasteride, medicinal chemistry, antibenign prostatic hyperplasia drug
