The present invention refers to a new efficient process for the synthesis of the active pharmaceutical ingredient Lapatinib and salts thereof.
In particular, the present synthesis is carried out employing new intermediates in which the amine function is protected by a group cleavable in basic milieu that provides a higher overall yield of the synthesis process.
本发明涉及一种新的高效合成活性药物成分Lapatinib及其盐的过程。特别是,本合成过程采用新的中间体,在其中氨基功能被一种在碱性环境中可裂解的保护基所保护,从而提供了更高的合成总产率。
