- Efficient Process For Production Of Carvedilol Phosphate
-
A novel cost effective process for the synthesis of phosphate salts of 1-(9H-carbazol-4yloxy)-3-[[2-(2-methoxyphenoxy)ethyl] amino]-propan-2-ol, (carvedilol phosphate) of formula (II) with high yields and purity is disclosed. More particularly, the invention discloses a process for preparation of crystalline phosphate salts of carvedilol using various phosphate forming reagents such as phosphorous pentoxide, polyphosphoric acid, dipotassium hydrogen phosphate, ammonium dihydrogen ortho phosphate, and sodium dihydrogen ortho phosphate in solvents selected from Acetonitrile, acetone and tetrahydrofuran. The solvents used to prepare solvates of carvedilol dihydrogen phosphate are methanol, ethanol and isopropyl alcohol.
