Reaction Steps
Carvedilol (4_g) was dissolved in 39_mL pyridine by stirring at room temperature. 70 mL of water was then added dropwise until crystallization began. The solution was left at room temperature without stirring for about 80 hours, then the crystals were filtered through a buchner funnel and dried in a desiccator at room temperature (connected to air pump) until constant weight to yield carvedilol Form III.
