The synthesis and in vivo SAR of N-benzyl, N-aceto, and N-ethylene ether derivatives of 2-(2,2,2-trifluoroethyl)-5,6dichloro-benzimidazole as novel androgen receptor antagonists are described. SAR studies led to the discovery of 4-bromo-benzyl benzimidazole 17 as a more potent androgen receptor antagonist in the rat prostate (ID50 = 0.13 mg/day), compared with bicalutamide (ID50 = 0.23 mg/day).
