摘要:
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.
摘要:
The present invention relates to a process for the synthesis of 2-cyanophenylboronic acid and the esters and salts thereof of formula (II), which are intermediates of the synthesis of active pharmaceutical ingredients such as Perampanel or E2040. formula (II): (II).
摘要:
Impurities of lapatinib such as N-{3-chloro-4-[(2-fluorobenzyl)oxy]phenyl}-6-[5-({[2-(methylsulfonyl)ethyl]amino}methyl)furan-2-yl]quinazoline-4-amine compound of formula (I) or a salt thereof: and analytical methods for identifying and quantifying such impurities of Lapatinib and salts thereof are provided. Also provided is Lapatinib containing less than about 0.05 percent of this and related impurities and methods for preparing such pure forms of Lapatinib.
