Fibrane the reduced derivative of fenofibrate

Abstract

Synthetic routes for the preparation of (i) isopropyl 2-(4-(4-chlorobenzyl)phenoxy)-2-methyl propanoate (Reduced Fenofibrate, Fibrane) (2) from isopropyl 2-(4-(4-chlorobenzoyl)phenoxy)-2-methylpropanoate (Fenofibrate) (1) in a single step is established in good yield and purity under mild conditions. The newly synthesized derivative of Fenofibrate has been characterized by NMR and IR spectroscopy techniques. Selective conversion of biphenyl ketone moiety, in the presence of ester carbonyl group in Fenofibrate to its corresponding alkane can be performed by Pd catalyst reduction with hydrogen transfer agent ammonium formate.
