Procedure
In a manner similar to example AIV-2-1, 4-[5-(4-fluoro-benzyl)-2,3-dimethoxy-phenyl]-2,4-dioxo-butyric acid ethyl ester was formed and the crude material was hydrolyzed in a manner similar to example AIV-3-1 using 1N NaOH to afford L3 as a yellow solid. Rf=0.67 (6:6:94 MeOH/AcOH/CH2Cl2). 1H NMR (400 MHz, CDCl3) δ7.38 (s, 1H), 7.25 (m, 1H), 7.14 (m, 2H), 7.00 (m, 2H), 6.88 (m, 1H), 3.94 (s, 2H), 3.90 (s, 3H), 3.85 (s, 3H). mass spec (FAB, M+1) 361 m/e.
