Abstract4-4-Fluorophenyl-2-2-methylpropanoyl-4-oxo-N-diphenylbutanamide is a key intermediate of atorvastatin. It was synthesized by condensation of isobutyrylacetanilide obtained from isobutyric acid by chlorinationcondensation with meldrum's acid and ammomolysis and 2-bromo-1-4-fluorophenyl-2-phenylethanone. The latter was synthesized from phenylacetic acid by chlorinationacylation and bromination. The starting materials in the synthetic route were easily available and the yield was reasonable. The structures of the main intermediates were identified by infrared spectrummass spectrum and 1H NMR. |
