Procedure

Combine 3,3-Bis-[4-(tert-butyl-dimethyl-silanyloxy)-3,5-dimethyl-phenyl]-1,3-dihydro-indol-2-one (0.886 g, 1.47 mmol), p-tolylboronic acid (0.40 g, 2.94 mmol), copper (II) acetate (0.267 g, 1.47 mmol), triethylamine (0.41 mL, 2.94 mmol), 4 angstrom molecular sieves, and dichloromethane (20 mL). Stir at room temperature overnight under ambient atmosphere. Filter the reaction through Celite. Elute through a column of silica gel with 70% dichloromethane in hexanes and concentrate. Dissolve the resulting compound (0.340 g, 0.492 mmol), in THF (2 mL). Add a solution of tetrabutylammonium fluoride (1.0 M) in THF (1.23 mL). Stir for 1 h. Add 1N aqueous HCl(10 mL), water (40 mL), and ethyl acetate (50 mL). Separate the layers and concentrate the organic layer in vacuo. Chromatograph on silica gel eluting with ethyl acetate to give 0.215 g (32%) of the title compound: mass spectrum (FAB): m/z=464(M+1); 1H NMR(DMSO-d6): δ8.23 (s, 2H), 7.37-7.28 (m, 5H), 7.21 (td, 1H), 7.08 (td, 1H), 6.74-6.73 (m, 5H), 2.37 (s, 3H) 2.07 (s, 12H).
