실험 절차

To a solution of 6-hydroxy-1-tetralone (2.0 g, 12.3 mmol) in ACN (30 mL) was added (bromomethyl)cyclopropane (2.0 g, 14.7 mmol) and K2CO3 (3.4 g, 24.6 mmol) at rt. The mixture was heated at 80° C. overnight. After the reaction was cooled to rt, it was diluted with EtOAc, filtered, and concentrated. The residue was purified by column chromatography (20:1 PE/EtOAc) to give 2.3 g (87%) of the title compound as a yellow solid. 1H NMR (300 MHz, CDCl3): δ 0.35-0.40 (2H, m), 0.65-0.71 (2H, m), 1.25-1.32 (1H, m), 2.08-2.16 (2H, m), 2.62 (2H, t, J=6.3 Hz), 2.93 (2H, t, J=6.0 Hz), 3.87 (2H, d, J=7.2 Hz), 6.71 (1H, s), 6.83 (1H, dd, J=2.1, 8.4 Hz), 8.01 (1H, d, J=8.4 Hz).
