YieldReaction ConditionsOperation in experiment
97% With potassium carbonate In acetone for 6 h; Reflux General procedure: 6-Hydroxy-1-tetralone (0.3 g, 1.85 mmol) was suspended in acetone (15 mL) containing K2CO3 (3.70 mmol). The reaction was treated with an appropriately substituted arylalkyl bromide (2.035 mmol) and heated under reflux for 6 h. The reaction progress was monitored using silica gel TLC with ethyl acetate:petroleum ether (1:2) as mobile phase. Upon completion, the reaction was filtered through a pad of celite and concentrated in vacuo. The crude thus obtained was purified by recrystallization from cyclohexane.

94% With potassium carbonate In acetonitrile at 50℃; for 2 h; Step 1:
Preparation of 6-benzyloxytetralin-1-one
To a solution of 6-hydroxytetralin-l-one (100 g, 616.56 mmol, 1.00 eq) in acetonitrile (1000 mL) was added potassium carbonate (170.43 g, 1.23 mol, 2.00 eq) and benzyl bromide (126.54 g, 739.87 mmol, 88 mL, 1.20 eq).
The reaction mixture was stirred at 50° C. for 2 hours. TLC (petroleum ether:ethyl acetate=5:1) showed most of the starting material was consumed.
Water (1000 mL) was added to the mixture, the resulting mixture was extracted with ethyl acetate (600 mL*3).
The combined organic phase was washed with brine (800 mL), dried over sodium sulfate, filtered and concentrated in vacuum.
The residue was triturated with petroleum ether and ethyl acetate (303 mL, petroleum ether:ethyl acetate=100:1, V:V).
The mixture was filtered and the filter cake was washed with petroleum ether (50 mL*2), dried in vacuum to give 6-benzyloxytetralin-1-one (146 g, 578.65 mmol, 94percent yield) as a brown solid. 1H-NMR (400 MHz, CDCl3) δ 8.02 (d, J=8.8 Hz, 1H), 7.45-7.34 (m, 5H), 6.91 (dd, J=8.8, 2.4 Hz, 1H), 6.80 (d, J=2.4 Hz, 1H), 5.12 (s, 2H), 2.93 (t, J=6.0 Hz, 2H), 2.62 (t, J=6.4 Hz, 2H), 2.15-2.09 (m, 2H).

The mixture was filtered, concentrated and the residue was purified by flash column chromatography eluted with 0-10percent EtOAc in petroleum ether to afford 129a (26 g, 84percent yield) as brown oil. 1H NMR (400 MHz, CDCl3) δ 8.06-7.98 (m, 1H), 7.46-7.32 (m, 5H), 6.90 (d, J=8.8 Hz, 1H), 6.80 (s, 1H), 5.16-5.08 (m, 2H), 2.93 (t, J=6.0 Hz, 2H), 2.62 (t, J=6.4 Hz, 2H), 2.17-2.06 (m, 2H).

The mixture was cooled to 10 °C with an ice bath, filtered and washed with small amount of acetone. The filtrate was concentrated in rotavap. The resulting crystals were collected by filtration and washed with EtOAc-hexane then hexane to give a pale yellow solid product as the first crop. The mother liquid was concentrated in rotavapor and the residue was purified by chromatograph with EtOAc:hexane (0:100 to 20:80) to give the second crop of solid product (38.07g, 80percent). 1H NMR (CHLOROFORM-d) δ: 8.02 (d, J = 8.6 Hz, IH), 7.32 - 7.51 (m, 5H), 6.91 (dd, J = 8.8, 2.3 Hz, IH), 6.80 (s, IH), 5.13 (s, 2H), 2.93 (t, J = 6.1 Hz, 2H), 2.56 - 2.68 (m, 2H), 2.12 (quin, J = 6.3 Hz5 2H).
