Reaction Steps

To a solution methyl (R/S)-(5-trifluoromethylsulfonyloxy-indan-1-yl)acetate (2.63 g, 7.80 mmol, from Step D) in N-methylpyrrolidinone (20 mL) under argon, zinc cyanide (733 mg, 6.24 mmol), Pd2 dba3 (36 mg, 39.0 μmol) and dppf (52.0 mg, 93.6 μmol) were added, and the reaction mixture was heated to 100° C. After 16 hr, the reaction mixture was concentrated iji vacuo and partitioned between EtOAc and H2O. The layers were separated and the organic layer was washed with H2O, brine and dried over MgSO4. The mixture was filtered, the filtrate concentrated in vacuo, and the residue purified by flash chromatography (5, 10% EtOAc/hexanes) on SiO2 to give 1.40 g of the title compound as a white solid: 1H NMR (CDCl3) δ 1.80-1.84 (m, 1H), 2.43-2.48 (m, 1H), 2.52 (dd, 1H, J=8.5, 15.8 Hz), 2.77 (dd, 1H, J=6.0, 15.8 Hz), 2.92-3.00 (m, 2H), 3.62-3.66 (m, 1H), 3.74 (s, 3H), 7.27 (d, 1H, J=5.5 Hz), 7.47 (d, 1H, J=7.8 Hz), 7.51 (s, 1H).
