Reaction Steps
A mixture of (5-Bromo-2,3-dihydro-1H-inden-2-yl)methanol (10 g, 44 mmol), Zn(CN)2 (10.3 g, 88 mmol) and Pd(PPh3)4 (1 g, 0.88 mmol) in 100 mL of DMF was heated at 100-120° C. under N2 atmosphere overnight. Most of the solvent was concentrated and the residue was partitioned between water (100 mL) and EtOAc (100 mL) and separated. The aqueous layer was extracted with EtOAc (50 mL×2). The combined organic layers were washed with brine (200 mL), dried over Na2SO4 and concentrated to dryness. The residue was purified with column chromatography (EtOAc/PE=1:20) to give the title compound. 1H-NMR (400 MHz, CDCl3) δ 7.45 (s, 1H), 7.41 (d, J=7.6 Hz, 1H), 7.27 (d, J=8.0 Hz, 1H), 3.64 (d, J=6.6 Hz, 2H), 3.05-3.13 (m, 2H), 2.70-2.84 (m, 3H).
