The present invention relates to an improved process for the preparation of macitentan and pharmaceutical acceptable salts thereof. Further present invention also relates to methylene chloride solvate of macitentan and their use in the preparation of pure macitentan.
The Discovery of <i>N</i>-[5-(4-Bromophenyl)-6-[2-[(5-bromo-2-pyrimidinyl)oxy]ethoxy]-4-pyrimidinyl]-<i>N</i>′-propylsulfamide (Macitentan), an Orally Active, Potent Dual Endothelin Receptor Antagonist
medicinal chemistry program aiming at the identification of novel potent dual endothelin receptor antagonists with high oral efficacy. This led to the discovery of a novelseries of alkyl sulfamide substituted pyrimidines. Among these, compound 17 (macitentan, ACT-064992) emerged as particularly interesting as it is a potent inhibitor of ETA with significant affinity for the ETB receptor and shows excellent
