Procedure

Carvedilol (4 g) was dissolved in 180 ml, Hexane/IPA in a ratio 1:1 by heating the mixture under stirring at 55° C. water bath. The solution was allowed to sit at room temperature without stirring for about 15 h, then the resulting crystals were filtered through a buchner funnel and dried in a desiccator (connected to air pump) at room temperature until constant weight to yield Carvedilol Form III.
