Procedure
In a manner similar to example AIV-2-1, 4-[3-(2,4-difluoro-benzyl)-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 L2 as a yellow solid. Rf=0.60 (6:6:94 MeOH/AcOH/CH2Cl2). 1H NMR (400 MHz, CDCl3) δ7.85 (m, 2H), 7.45 (m, 2H), 7.13 (m, 2H), 6.82 (m, 2H), 4.03 (s, 2H). mass spec (FAB, M+1) 319 m/e.
