LODINATION of aniline containing compounds: LODINATION was accomplished using a procedure similar to that set forth in the following reference which is herein incorporated by reference in its entirety for all purposes as if fully set forth herein: J. Med. Chem. 2001,44, 6,917-922. The ANTHRANILIC ester in EtOH was added to a mixture of silver sulfate (1 equivalent) and 12 (1 equivalent). The reaction was typically done after 3 hours at room temperature. The reaction was filtered through Celite and concentrated. The residue was taken up in EtOAc and washed with aqueous saturated NAHC03 (3x), water (3x), brine (1X), dried (MGS04), filtered, and concentrated. The crude product (-5 g) was dissolved in MeOH (60-100 mL), NAOH 6 N (25 mL), and water (250 mL). The reactions were typically done after heating at 70-80 C for 4 hours. The reaction mixture was extracted with EtOAc (2x), neutralized with aqueous HCI, filtered to collect the solids, and the solid products were washed with water. The products were dried in vacuo.
