Reaction Steps
To a solution of 6-bromo-1-indanone (prepared as described by Cornelius, Lyndon A. M. and Combs, Donald W. Synth. Commun. (1994), 24(19), 2777-88) (1.4 g, 6.57 mmol) in 20 mL of methanol was added sodium borohydride (0.087 g, 2.3 mmol) over a period of five minutes at room temperature. The reaction mixture was stirred for two hours at room temperature, concentrated under pressure and partitioned between ethyl acetate (50 mL) and 1N HCl (20 mL). The ethyl acetate layer was dried over sodium sulfate and concentrated under reduced pressure to yield the title compound as a solid (1.4 g, 99%). 1H NMR (CDCl3): δ 7.45 (s, 1H), 7.3 (d, 1H), 7.0 (d, 1H), 5.2 (t, 1H), 2.9 (m, 1H), 2.7 (m, 1H), 2.4 (m, 1H), 1.9 (m, 2H).
