Reaction Steps

To a solution of methyl (R)-(5-cyano-4-methyl-indan-1-yl)acetate (1.00 g, 4.36 mmol, from EXAMPLE 110, Step J) in pyridine (28 mL), acetic acid (15 mL), H2O (15 mL) and NaH2PO2 (3.07 g, 34.9 mmol) Rainey nickel was added (1.0 g) and the mixture was heated to 50° C. After 5 hr, the reaction was concentrated in vacuo and filtered through Celite®. The filtrate was concentrated in vacuo and partitioned between EtOAc (150 mL) and H2O (50 mL). The organic layer was washed with 5.0 N HCl (7×50 mL), sat. NaHCO3 (2×50 mL), brine (1×50 mL) and dried (MgSO4). The mixture was filtered, concentrated in vacuo and purified by flash chromatography (10% EtOAc/hexanes) to give 882 mg of the title compound as a white solid: 1H NMR (500 MHz, CDCl3) δ 1.76-1.84 (m, 1H), 2.41-2.51 (m, 2H), 2.57 (s, 3H), 2.78 (dd, 1H, J=5.5, 15.6 Hz), 2.81-2.87 (m 1H), 2.93-2.99 (m, 1H), 3.61-3.67 (m, 1H), 3.72 (s, 3H), 7.16 (d, 1H, J=7.8 Hz), 7.63 (d, 1H, 7.8 Hz), 10.2 (s, 1H).
