IMPROVED PROCESS FOR THE PREPARATION OF [3R,5R]-2-FLUOROPHENYL-β,δ- DIHYDROXY-5-(1-METHYLETHYL)-3-PHENYL-4-[(2-HYDROXYPHENYLAMINO)- CARBONYL]-1H-PYRROLE-1-HEPTANOIC ACID, SODIUM SALT

The present invention relates to an improved process for the preparation of [3R,5R]-2-fluorophenyl-β,δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(2-hydroxyphenylamino)-carbonyl]-1H-pyrrole-1-heptanoic acid sodium salt compound of formula- 1 represented by the following structural formula:

Synthesis of deuterium-labeled atorvastatin and its metabolites for use as internal standards in a LC/MS/MS method developed for quantitation of the drug and its metabolites in human serum

D5-labeled isotopomers of atorvastatin, atorvastatin lactone and its hydroxy metabolites were synthesized as internal standards for use in a LC/MS/MS method developed for the simultaneous quantitative determination of atorvastatin and its hydroxy metabolites in human serum. d5-Atorvastatin and d5-atorvastatin lactone were prepared from d5-aniline whereas their corresponding hydroxy metabolites were synthesized using d5-benzaldehyde.
