| titleOfInvention | Method of crystallisation of losartan potassium |
| abstract | The invention relates to a process for the preparation of crystalline form (I) of Losartan Potassium with formula which comprises reacting compound with formula wherein R represents hydrogen or triphenylmethyl (trityl) protecting group with potassium hydroxide in an alcohol, selected from the group comprising methanol, ethanol, butanol and mixture thereof. There follows concentration under reduced pressure to remove alcohol and addition of a settling agent selected from the group of acetone, ethylacetate, acetonitrile, toluene and mixtures thereof for the isolation of Lasartan Potassium. 4 claims, 2 figures |
