    • note
    • The phenol 24a resulted from the intramolecular nucleophilic attack of the anion of the acetamide (formed in the reaction conditions because of excess of sodium hydride) onto the ether adduct. This intermediate is formed by displacement of the fluoro group of 23a with sodium 2-acetamidoethoxide.

    • note
    • In the absence of amine, activation of the carboxylic acid with EDCI or HATU gave the activated anilide resulting from the intramolecular attack of the NH of the aniline onto the activated carboxylic acid; this activated anilide can be isolated and reacted with an amine to form the expected amide. Alternatively in the presence of the amine, activation of the carboxylic acid gave the expected amides with minor amounts of the activated anilide.

    • Good enantiomeric purity was observed with these methods: 19 and 21 made as described in Scheme 1 gave, respectively, 99.6% ee and >99.6% ee measured by chiral HPLC; 21 made in a similar manner as compounds in Scheme 2 gave 98.6% ee; however attempts to displace 23b with the (R)-N,N dimethyl lactamide in the presence of sodium hydride in THF at reflux gave partial racemisation.

    • Increased blood levels of 19 dosed at 100 mg/kg orally were seen after oral coadministration of 100 mg/kg of ABT (AUC 670 μM h vs 130 μM h without ABT and concentration at 8 h 23 μM vs 2 μM).
