The present invention discusses a novel process for the synthesis of [R- (R*,R*)]-2(4-fluorophenyl)-B,D-dihydroxy-5-(1-methylethyl)-3-phenyl-4- [(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemi calcium, atorvastatin form V. The compound so prepared is useful as inhibitors of the enzyme HMG-CoA reductase and are thus used as hypolipidemic and hypocholesterolemic agents.
La présente invention concerne un nouveau procédé de synthèse d'un sel d'hémi-calcium d'acide [R-(R*,R*)]-2(4-fluorophényl)-B,D-dihydroxy-5-(1-méthyléthyl)-3-phényl-4-[(phénylamino)carbonyl]-1H-pyrrole-1-heptanoïque, soit la forme V de l'atorvastatine. Le composé ainsi préparé est utile en tant qu'inhibiteur de la HMG-CoA réductase et il est par conséquent utilisé en tant qu'agent hypolipidémique et hypocholestérolémique.
