Procedure
A mixture of ethyl 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indene-2-carboxylate (16 g, 50% purity, 25.3 mmol), NaIO4 (24 g, 0.112 mol), CH3COONH4 (5.2 g, 0.068 mol), acetone (100 mL), and water (10 mL) was stirred at room temperature overnight. The acetone was evaporated, and the aqueous residue was extracted with EtOAc (3×100 mL). The organic layer was dried over MgSO4 and concentrated in vacuo to afford the title compound as white solid (3.5 g). 1HNMR (400 MHz, DMSO-d6): δ 7.91 (s, 2H), 7.62 (s, 1H), 7.57 (d, 1H), 7.17 (d, 1H), 4.10 (q, 2H), 3.36-3.32 (m, 1H), 3.09-3.07 (m, 4H), 1.20 (t, 3H).
