Reaction Steps
Carvedilol (4 g) was dissolved in 195 mL mixture of water/methanol (in a ratio 1:3 respectively ) by heating the mixture under stirring in 55° C. water bath. The solution cooled to ambient temperature and left at ambient temperature without stirring for about 15 h, the crystals were filtered through a buchner and dried in a desiccator at room temperature (connected to air pump) until constant weight to yield carvedilol Form III.
