Abstract

The present disclosure provides compounds of Formula (IA) and or pharmaceutically acceptable salts thereof that are tyrosine kinase inhibitors, in particular BTK, and are potentially useful for the treatment of diseases treatable by inhibition of tyrosine kinases such as cancer, inflammatory diseases such as arthritis, and the like. Also provided are pharmaceutical compositions containing such compounds and/or pharmaceutically acceptable salts thereof and processes for preparing such compounds and pharmaceutically acceptable salts thereof.
