Definitions
- the compounds of formula I can be prepared by a novel process comprising, a) a) halogenation of compound of formula II to afford a compounds of formula HI, b) reaction of compounds of formula III with compounds of formula IV.
- G any alkyl or aryl
- HMG Co-A reductase inhibitors are important intermediates for the preparation of drug molecules especially, HMG Co-A reductase inhibitors.
- the HMG Co-A reductase inhibitors are useful as inhibitors of the enzyme 3-hydroxy-3- methylglutaryl-coenzyme A reductase (HMG CoA reductase) and are thus useful as hvpolipidemic or hypocholesterolemic agents.
- G any alkyl or aryl
- FORMULA I The process of the present invention is new, economical, and commercially feasible method for preparing intermediates used for the preparation of HMG CoA reductase inhibitors.
- reaction between compounds of formula II and III is carried out in the presence of reagents selected from Bromine, N-bromosuccinimide, thionyl chloride, Br 2 (CN) 2 , 4-(dimethylamino)pyridinium bromide or any such suitable halogenating agent.
- reagents selected from Bromine, N-bromosuccinimide, thionyl chloride, Br 2 (CN) 2 , 4-(dimethylamino)pyridinium bromide or any such suitable halogenating agent.
- the compounds of formula III can be further used for preparation of 4-
- Fluoro- ⁇ -[2-methyl-l-oxopropyl] ⁇ -oxo-N- ⁇ -diphenylbenzene butane amide which is key intermediate for manufacture of [R-(R*,R*)]-2-(4-Fluorophenyl)-B,D-Dihydroxy- 5-(l-Methylethyl)-3-Phenyl-4-[(Phenyl amino) Carbonyl]-lh-Pyrrole-l-Heptanoic Acid, by reacting with compound of formula IV.
- the reaction between compounds of formula III and formula IV is carried out in the presence of reagents selected from Lithium diisopropylamide, sodium hydride n-butyllithium, sodium ethoxide or any such suitable base.
