PROCESS FOR PREPARATION OF CANDESARTAN CILEXETIL CRYSTALLINE POLYMORPHS

摘要

The present invention relates to processes for preparation of candesartan cilexetil crystalline polymorphs. Thus, for example, candesartan cilexetil is added to toluene, the contents are heated to reflux, stirred for 15 minutes at reflux and the resulting crystals are collected at 0 -5aC by filtration to give candesartan cilexetil crystalline form III.
