    • Attempts to oxidise the benzylic alcohol 4a resulted only in formation of phthalimide 27(oxidation with PDC was also attempted but resulted in no detectable aldehyde formation). Attempts to convert the hydroxyl group to a leaving group and displace with amines resulted in formation of lactam 28{A figure is presented}.

    • Studies with mdr1a/b knockout mice (in the presence and absence of GF120918, a potent P-gp and BCRP inhibitor) indicated the poor oral exposure of 4j was not due to P-gp or BCRP-mediated efflux.
