GETTING IRBESARTANA |
| abstract |
The present invention relates to a method for producing irbesartan or its pharmaceutically acceptable salts, including the synthesis of tritylrbesartan using the reaction of 5- (4- (bromomethyl) biphenyl-2-yl) -1- (triphenylmethyl) tetrazole and 2-n-butyl-4-cyclopentane -2-imidazolin-5-one or its salt in an organic solvent in the presence of a phase transfer catalyst and a base, removal of the protective group and isolation of irbesartan or its pharmaceutically acceptable salt. |
