Preparation of an atorvastatin intermediate using a paal-knorr condensation |
| abstract |
A process for preparing a compound of formula (I): comprises reacting a 1,4-diketone of the formula (II): with a primary amine of the formula (III): wherein R1 and R2 may be the same or different and are selected from any one or more of H; C1-C6 alkyl which may be straight or branched, substituted or unsubstituted with a halogen group; C1-C6 alkoxy group; or R1 and R2 together represent an alkylidene group of the formula CRaRb wherein Ra and Rb may be the same or different and are selected from any one or more of a C1-C11 alkyl group, and R3 is selected from any one or more of a C1-C6 alkyl group, in the presence of a catalyst, the catalyst comprising a salt wherein the salt comprises an amine salt or an inorganic salt of an organic acid. |
