PREPARATION OF 3-PYRROLE SUBSTITUTED 2-INDOLINONE DERIVATIVES

摘要

The present invention relates to novel intermediates and further to the use of said intermediates in processes for the preparation of indolinone derivatives, in particular 3- pyrrole substituted 2-indolinones having amide moieties on the pyrrole ring. Such compounds are useful in die treatment of abnormal cell growth, such as cancer, in mammals.
